Oh may gosh, I really don't want to get too involved in this, but I do want to point out there is a Federal estate tax (aka the death tax) that I believe probably serves as much or more as social engineering purpose as it does a revenue generator.
For those unfamiliar with it, I'll try to summarize about a million words of tax law into 50 or so:
When you die, the Federal government takes part of your net worth as a tax. Let's call the rate 40% for discussion purposes. So, in a nutshell, if Bill gates dies tomorrow, and his net worth is 20 Billion, then 8 billion goes to the government, and 12 to his heirs.
Now, as Ouchie or anyone else involved in the tax law will tell you, there are multiple, multiple caveats and exceptions to the above basic proposition. For example, if your net worth at death is less than 11 million or so, you're completely exempt from this tax, and the entire amount of your net worth goes to your heirs (which I agree with 1000%, and I personally would make all estates of less than 50 million exempt from the death tax).
However, I did want to point out this morning that there is a mechanism in place to prevent families from accumulating wealth unchecked. The tax applies to each generation. So every time a family's wealth is passed down to the children, the government takes a sizable chunk. And I support this. I don't want the Gates Family accumulating so much wealth that they decide to buy Maine, and the estate tax (aka the "death" or "transfer" tax) is one way to prevent this.
I'm not going to argue the merits of the estate tax beyond this post. If you hate it or like it or think that it doesn't work right, great. No tax law is perfect. But I'm on the record as saying it helps America stay America, and helps to prevent an oligarchy situation.
Carry on!
