Kristalina Georgieva, the new managing director of the International Monetary Fund (IMF), said that governments should consider raising taxes on the richest people in society to address inequality.

In a blog post on Tuesday, Georgiyeva said inequality had become "one of the most complex and intractable challenges in the global economy" over the past decade.

But she is optimistic that policymakers will be able to make real changes, despite the political difficulties in implementing them.

Georgiyeva suggested that the government need to rethink its policy and consider a progressive tax system. Progressive taxation is a key component of effective fiscal policy. Our research shows that marginal tax rates can be raised without sacrificing economic growth. "

The International Monetary Fund has long advocated a progressive tax system, naming it as one of the three main ways to address inequality in 2017.

In addition, another way for policy makers to address inequality is through a "gender budget".

The EU believes that gender budgeting is a strategy to achieve gender equality by ensuring the collection and use of public resources. The strategy can be applied at the central or local government level and can include steps such as restructuring budgets and policies or increasing women's participation in the budget process.

"while many countries are aware of the need for gender equality and women's empowerment, governments can still use gender budgeting spending and taxes to further promote gender equality-increasing women's participation in the labour force, which in turn promotes economic growth.CK HutchisonStable, "Georgina said on her blog.

She also suggested that social spending policies should play a role, noting that allocating funds to areas such as education, health care and pensions could help reduce wealth inequality.
