And this whole thing about "fair share" goes back to politics and socialism again. In reality, what business is it of the goverment how much money I make? What determines how "fair" it is if I double my salary and the govermentment takes over half of my gain? Only socialists talk about "fair share" to hide their politics in compasion. What they really believe is that anyone makeing over enough to just get by needs to pay most of their additional income in high tax rates, "to keep it fair".
They want equal outcome, not equal opportunity (but not for them of course, they need to paid highly because they are the smart ones, and they will need to determine who get what and to come up with the next five year plan).
This game can't go on forever, you can take from the rich and give to an increasing number of poor and not expect the poor to share the cost of goverment. At some point you cross the line of diminishing returns and "the rich" will give up as most of their wealth will be spent or taken. Then what?
i don't think this reasoning is correct. "the rich" are in no danger of losing their wealth because they are not taxed on their wealth, but only on their increase.
someone will say, well what about property tax and estate tax? and i agree, these are unfair.
