Your 'average' is bullshit

"The top 1 percent of taxpayers, or those with incomes over $506,210, would pay an average of $73,633 more in taxes. Much of that burden is concentrated at the very top of the income scale."

If you are single and have taxable income of $506,000 a year you will pay an additional $4,876 in income taxes. That's 4.6% (35% to 39.6%) of the amount over $400,000. Nothing changes for the first $400,000.
