So, uhh, one kind of tax is different from another? Really? They all seem to cut into my bottom line just the same, no matter which govt entity collects them.
Taxes that are insignificant to high earners matter to middle and lower income people. SS, for example, takes 6.25% of every working stiff's wages, but shrinks to insignificance for hedge fund managers. No Medicare taxes on dividends & capital gains, either. No sales taxes on real estate, businesses, stocks & bonds.
Sales tax matters to low income earners, means nothing to very high earners, and it's the same story wrt a lot of other regressive & often hidden taxes & fees. Gas tax. Excise tax. So forth & so on. Hell- John McCain didn't know what kind of car he was chauffered around in, let alone the price of gas or how much of that was tax. It didn't matter to him.
The long & short of it is that very large parts of small incomes are spent on taxable items, and very large parts of very large incomes aren't. That's reflected in total taxes paid as a % of income by earners at different levels, with the big picture being that total taxes are a lot flatter than what you believe or represent them to be.

I could cover the page with links, but you wouldn't read 'em, anyway, because your ideas are warped by a defective belief system, one that worships greed as the one true God, and the greediest among us as seers, prophets, and high priests. Facts that don't fit into that are automatically rejected, deepening your disconnect from reality. Enjoy your delusions while you can.
