Maybe if you stopped with the sarcasm and thought about this critically you'd see that the solution isn't taxing everyone to death, but reducing the out-of-control government spending. Because at the rate the government is spending money, you will be paying this "capital gains" tax in 2 decades on a much smaller balance.
A new type of tax on the absolute wealthiest of the wealthy is not "taxing everyone to death." I'm sure there are some great ways we can reduce/improve government spending, but that is completely separate from the idea that the mega-rich should be paying more.
