Wealth concentration has reached levels in many countries not seen since the Gilded Age of the early twentieth century. The richest one percent of the global population now owns more wealth than the bottom fifty percent combined. How this happened, and what — if anything — should be done about it, is one of the most contested questions in contemporary politics.

From a conventional economic perspective, some degree of inequality is considered necessary to incentivise innovation, risk-taking, and productive labour. The question is where that degree becomes counterproductive — when inequality reduces social mobility, undermines trust, and generates political instability.

Governments have several fiscal policy tools at their disposal. Progressive taxation — where higher earners pay a larger percentage — redistributes income. But capital gains, particularly from property and financial assets, are often taxed at lower rates than labour income, which critics argue reinforces wealth concentration rather than addressing it.

Monetary policy also has distributional consequences. Low interest rates, which prevailed for over a decade after the 2008 financial crisis, inflated the value of assets like property and shares — benefiting those who already owned them while making it harder for younger workers to buy homes or build wealth.

Universal basic income has emerged as a proposed redistributive policy to address these structural shifts. Proponents argue it would reduce poverty, support those displaced by automation, and address market failures in care work. Critics argue it is unaffordable and could reduce incentives to work. The debate reflects deeper disagreements about the proper role of markets, the state, and individual agency in determining economic outcomes.
