In that case, the more "fair" solution is high inheritance tax (maybe it's already in place?).

Discouraging long-term investment through high capital gain is not a good solution.

I have no idea if you should, but in the US, you probably will. Depending on what year you inherited the money, you'll have paid up to 55%.

That seems reasonable. My problem is with the party that wants to abolish the estate tax and cut capital gains taxes.
