The truth is that many people who earn six figure incomes are very much in the middle class: their income is often attendant to small business ownership and in any event is currently subject to such a high level of taxation at the Federal, state, and local levels that its purchasing power is far less than commonly supposed.
Another harsh truth is that nearly 43% of American adults pay no income taxes at all, and are thus not paying their fair share. But try getting elected on that platform.
“and are thus not subject to Federal income taxes.”
Which will be eventually subjected to Federal confiscations.
