First of all, by truncating my original post you're showing yourself to be intellectually dishonest and sidestepping the question of who the 47% are that pay no federal income taxes.<quoted text>
Ordinary income is usually guaranteed. If you work a certain amount of time, you are legally entitled to the pay that you were offered when you took the job. Capital gains involve risk. They are not guaranteed. You can invest your money and lose it all. Moreover, the year when you receive capital gains may not be the same as the years when they were earned.
It would appear that you are the idiot, or at the very least deliberately dishonest in your assertion.
But to respond to your narrow interpretation my response is so what? Sure there's risk involved but there's also risk in a trip to the blackjack table. Why not give a special rate for gambling winnings?
Most of those who get their income from investments don't keep all their eggs in one basket and can leverage their losses against their gains at tax time. If you put all of your cash into a single investment and you lose then those are the breaks.
