And don't forget where Biden (just like the Republicans) got their enormous campaign contributions. From the super-rich. He will go easy on them and largely burden the richer in the middle class, because why should the Democrats hurt themselves by alienating their best donors.
The burden will obviously fall on the middle class, because as per Biden's plan, anyone with a taxable income of more than $400,000 will witness a tax increase. Imagine this, the top earners is states like California and New York are all ready paying 55% to 60% of their income as tax. If you increase it any further, then these people will have only a small portion of their salary remaining after tax deductions. This is why I suggested lowering the tax rate, but at the same time removing all the tax exemptions.
