Income inequalities seem to be widening. But this may not be a uniquely British problem. Recent studies show that global economic convergence — the process by which poorer countries catch up with richer ones — is slowing. For two decades, developing nations grew faster than advanced economies. That era has ended. Poor countries are no longer gaining ground on rich ones at the pace they were, and in some regions the gap is widening again. The World Bank assesses that nine out of ten people now live in countries with high inequality. Can the world be put on a fairer path to growth?
For the UK and Scotland, these global trends matter because they are a symptom of a polarised economic environment. Multinational corporations are capturing a larger share of global profits, whilst smaller domestic firms struggle. The biggest companies now account for the bulk of corporate earnings, but their gains are increasingly detached from the communities around the world where they operate. More than forty percent of all wealth generated since the start of this century has flowed to the wealthiest one percent, while the bottom half of the world's population received barely one percent. Individual nations struggle to tax global businesses for their activities in a particular jurisdiction. Although many corporations have stockmarket investors and public listings, genuine accountability seems diminished.
International efforts to address this have made some progress but remain fragile. The OECD and G20 have pursued a global minimum corporate tax framework, designed to prevent countries from undercutting each other with low rates and to ensure multinationals pay a fairer share in the countries where they actually do business. Yet the politics of implementation remain fraught. With major economies pulling in different directions, the prospect of a coherent international settlement that properly captures the profits of global technology and financial firms remains elusive. The structural incentives favouring capital concentration have not yet been seriously challenged.
Added to this increasing concentration in global business, the productivity benefits of Artificial Intelligence seem likely also to be spread unevenly. AI offers the prospect of detaching a large portion of economic activity from individual labour. In advanced economies, around sixty percent of jobs may be affected in some way by AI, with roughly half of those exposed roles potentially benefiting from augmentation while the other half face displacement of tasks currently performed by humans. Crucially, gains in productivity from firms that adopt AI are likely to boost returns to capital, which tends to favour those who already own assets. Despite the potential for social upheaval, there remains little serious public debate about what this should mean for the tax system and government policy. The question of who ultimately benefits from AI-driven growth deserves far more attention than it is currently receiving.
Something fundamental has shifted in how prosperity is shared globally, and Britain is impacted more than most. Our economy continues to grow, albeit slowly, but most people are seeing little benefit. For a brief period following the financial crisis, low-income workers made genuine gains. Labour shortages gave bargaining power, and wages at the bottom began rising faster than those at the top. That progress has now reversed. Top earners are pulling ahead while wages for the bottom third have stagnated.
The statistics on household incomes are stark. The most recent official data show that median income for households in the lowest ten percent increased by just two percent in real terms in the latest financial year, compared to significantly stronger gains further up the distribution. In Britain today, the richest fifth of households receive disposable incomes more than four times higher than the poorest fifth. Among developed nations, only the United States shows greater disparity. Meanwhile, several small European countries demonstrate that advanced economies can distribute their wealth far more evenly. The Gini coefficient for UK income inequality stands at thirty-seven percent when measured after housing costs — a figure that tells us something important about the relationship between housing markets and living standards, and the degree to which property wealth amplifies underlying income differences.
The roots of this inequality run deep. Britain has long struggled with a productivity problem that became acute after the financial crisis. Between 2000 and 2007, productivity grew at over two percent annually. Since 2011, that figure collapsed to half a percent, and since the pandemic to just two tenths of a percent. This matters because productivity drives living standards. When an economy fails to produce more value per hour worked, real wages stagnate and growth slows. The challenge is compounded by regional concentration. London dominates national output, with median household income well above the UK average, while large parts of the Midlands and the North continue to trail significantly. Scotland has its own regional disparities, and while capital investment has been increasing, productivity performance across Scotland's regions remains uneven.
Britain now invests far less than comparable nations. For thirty years, investment rates have lagged behind the rest of the G7. Infrastructure, research and the tools that would make the workforce more productive have all been underfunded relative to peer economies. British workers are consequently less productive than their counterparts in France, Germany and the Netherlands. The consequences are now structural. A lower capital stock means lower output per worker, which flows directly into stagnant wages and constrained public revenues. The cycle is self-reinforcing and requires deliberate intervention to break.
Scotland faces particular challenges in this context. The CBI and Fraser of Allander Institute have highlighted that Scotland continues to struggle with slower productivity growth than the UK average, weaker export orientation and persistent regional disparities in business dynamism. Planning delays, regulatory uncertainty and infrastructure gaps compound the picture. Of the businesses that do export, a handful of very large firms account for the vast majority of export value, leaving Scotland's economic base narrow and vulnerable. The Scottish Government's National Strategy for Economic Transformation sets out ambitions for a fairer, greener economy, but the proliferation of strategy documents — more than fifty currently active — without clear implementation has drawn justified criticism. Good intentions need to be translated into investment decisions, planning approvals and measurable outcomes.
Breaking out of this pattern requires confronting uncomfortable truths. Britain needs sustained economic growth of two percent or higher, maintained over many years, to generate the tax revenue and rising living standards that improve public services and reduce social tension. Greater incentives for business investment and entrepreneurship are essential. But growth alone will not solve the distributional problem if the returns continue to flow disproportionately to capital owners and highly-paid professionals. The design of the tax system, the strength of labour market institutions and the quality of public investment all determine whether growth translates into broad-based prosperity or simply compounds existing inequalities.
The world must develop public policy that addresses some unhealthy business trends. The power of governments relative to large corporations has weakened, and a genuine debate is needed on holding those corporations to account in the jurisdictions where they generate their wealth. Encouragingly, international forums have begun to acknowledge that inequality is not simply a social concern but an economic one — that excessive concentration of income and wealth reduces aggregate demand, undermines social cohesion and ultimately damages the conditions for sustainable growth. Whether that acknowledgement will be translated into policy change remains to be seen.
Scotland should be part of that international debate, not a passive observer of it. Scotland has genuine assets — in renewable energy, life sciences, financial services and higher education — that could underpin broad-based prosperity if investment is sustained and the benefits properly distributed. But harnessing those assets requires productivity growth, infrastructure investment and policies that ensure the gains from economic expansion are shared across regions, sectors and income groups. The choice is not between growth and fairness. They are, in the long run, the same objective.
