Liberals are envious and want to believe anyone who is wealthy had to cheat to get their money.
The top 10% currently pays 55% of all federal income taxes and 40% of earners pay 0 (many get refunded taxes they did not pay through the EITC). The top 40% pay 106% of all federal income taxes (because of the EITC).
The percent of total federal income taxes paid by the wealthy has been increasing over the years because their share of the income has been increasing--exactly the way progressive income taxes are supposed to work. In 1979 the top 10% paid 39.1% of all federal income taxes; today, they pay 55%. The wealthy are the only group who pay a higher percentage of federal income taxes than their share of total income--all other groups pay a smaller percent of income taxes than their share of income.
You miss so many parts of the taxation picture, it's hard to know where to start.
First of all income taxes make up a lower percentage of federal income than it did in 1979. 61% in 1979. 56% in 2017
Corporate owners pay the corporate income taxes out of their profits. Corporate income taxes have declined by almost 60% from 1979 to 2017 which means "rich" corporate owners have seen a corporate income tax decrease which you fail to account for.
But the real issue is how much of spending are the taxes paying for. In 1979, the deficit was 1.6% of GDP. In 2017 it was 3.5% of GDP. You can argue that the "rich" are paying more in income taxes but in reality it seems they are paying less of the federal spending in 2017 than they did in 1979.
The wealthy are the only group who pay a higher percentage of federal income taxes than their share of total income--all other groups pay a smaller percent of income taxes than their share of income.
By ignoring the other 43% of taxes you get to make a statement that has little meaning in the over all scheme of government revenues.
Let's examine that.
In 2017, for a person with a taxable income of $400,000, the federal government is collecting 35.9% of that last dollar. (33% income tax plus 2.9% Medicare split between employer and tax payer.)
For a person with a taxable income of $100,000 the federal government is collecting 43.3% of that last dollar. (28% income tax plus 2.9% Medicare and 12.4% Social Security split between employer and tax payer.)
A person making $10 million dollars not as a wage earner is only paying 39.6% on that last dollar. If that last dollar comes from capital gains then they are only paying 15%.
The real problem is that the government has long tried to balance it's budget on the back of the low income wage earners paying into Social Security. By not collecting enough in income taxes or other general revenue and borrowing from the SS trust fund, the government has hidden how much it is truly underfunded. Now that the borrowing from SS is coming due, rather than raising taxes where the true deficits have been, the government has decided to stiff the lower income wage earners.
There is no simple answer here but your simplistic numbers don't come close to giving a true picture of taxes and who pays them.
