Actually, i'am against high(er) income tax. in contrary, i' am agree with libertarians which say income should be completely tax free. But in my opinion, there should be a higher tax for gains on stocks larger than, let's say, 1 mln. The most rich people had worked hard to get rich but then they get richer just for letting there money work.
I don't agree with any of this. Why should there be higher tax for investing money in to the stock markets? The money, which is being invested has been already taxed once. You can't tax it again and again. And in almost all the countries, there are taxes on gains from stocks. If you increase the tax, then the rich will not invest in anything. They will just keep their wealth as hard cash.
