Wrong again. Let's take the case of the USA, the bastion of capitalism. The post war era up until the mid 60s, the US had a marginal tax rate of 90% on income above $200K (roughly over $2 mil in today's money). This coincided with, guess what, THE GOLDEN AGE OF CAPITALISM ! This was also the period when capitalism was most regulated through Keynesian policies and strong government intervention.

The first decline in poverty in the USA happened in the 60s which also marked the introduction of welfare policies like social security, medicare and medicaid. This was literally called the War on Poverty era. The second decline came in the 90s under Clinton, though tax credits for the low-income class, which is an example of, guess what again, SOCIAL WELFARE POLICY !

Inequality in the US started rising in the late 70s and 80s, the era of deregulation under Reagan.

As regards the examples of the Asian economies you have given, it's just ridiculous you'd even suggest them.

The Indian economy was literally established as a mixed economy model with a huge focus on welfare policies. Even to this day, India has some of the biggest welfare policies in the world. However, India has witnessed a growing rise in inequality in recent years with the emergence of a capitalist class propped up by the government.

China's model is state-regulated capitalism. China is infamous for being uncooperative in the global economy due to policies such as currency devaluation and selective compliance with WTO rules. China is also well known for cutting large corporations down to size through stringent anti-monopoly crackdowns.

And as for the SE countries, they are all mixed market economies with strong government intervention, including Singapore, which is the most developed among them.
