Got a couple interesting quotes from this article to show that other countries don't have the same amount of distributions as America does. Alongside this, the United States also has the most progressive income tax system out of the countries of its peers. It's peers also have some of the most regressive taxes in the world, which include the VAT system.
The poorest fifth of U.S. households receive 84.2% of their disposable income from taxpayer-funded transfers, and the second quintile gets 57.8%. U.S. transfer payments constitute 28.5% of Americans’ disposable income—almost double the 15% reported by the Census Bureau. That’s a bigger share than in all large developed countries other than France, which redistributes 33.1% of its disposable income.
The U.S. also has the most progressive income taxes of its peer group. The top 10% of U.S. households earn about 33.5% of all income, but they pay 45.1% of income taxes, including Social Security and Medicare taxes. Their share of all income-related taxes is 1.35 times as large as their share of income. In Germany, the top 10% pay 1.07 times their share of earnings. The top 10% of French pay 1.1 times their share.
Even these numbers understate how progressive the total tax burden is in America. The U.S. has no value-added tax and collects only 35.8% of all tax revenues from non-income-tax sources, the smallest share of any OECD country. Most developed countries have large VATs and collect a far larger share of their state revenue through regressive levies.
When all transfer payments and taxes are counted, the U.S. redistributes a larger share of its disposable income than any country other than France. Relative to the share of income they earn, the share of income taxes paid by America’s high earners is greater than the share of income taxes paid by their peers in any other OECD country. The progressive dream of an America with massive income redistribution and a highly progressive tax system has already come true. To make America even more like Europe, these dreamers will have to redefine middle-income Americans as “rich” and then double their taxes.
In all honesty, I probably didn't do the article much justice in my failure to explain everything -- though I do think this is a VERY interesting article and a good discussion.
