Only a democrat calls the high taxes on the rich a transfer of wealth.
The facts are complicated. Once the tax rate gets around 50% or higher on the rich like in the good old days, there are all kinds of efforts logically put into tax avoidance schemes with lots of loopholes being made available.
The big guilt in regards to the rich is when the government has policies that favor the rich and powerful in regards to schemes, loopholes,etc..
The tax rates on the rich have never been truly low as the Decocrats would have you think. Capital gains at 15% is an interesting issue. If you jack up the capital gains tax, people are less likely to sell their gains.
