so the answer is yes.
However, i did not go as far as proposing anything. You are assigning value on my statement.
I merely pointed out that it is a mute point to say that you can not use your unrealized gains.
That is true, but there is a theory, applied very weakly, that supports this. The idea is that a decedent's estate is subject to a wealth tax on its fair market value, therefore to also subject the unrealized gains within the estate to income tax would be double taxation, which is to be avoided. The flaw is that the exemption from the estate tax is relatively high (something like $13,000K), so there would not be any double taxation is most cases, but it's treated that way nonetheless.
One inherits free money - and pay inheritance tax of it. In order for capital to be free, capital gains tax needs to be paid.
And the general idea to protect against "double taxation" is meaningless. All money are constantly being taxed again and again.
Regardless. Inequality in itself is really bad, and Americans do feel the consequences.
If you can defer the repayment of the loan until after death, capital gains are eliminated.
The oldest trick in the book is to use unrealized gains as collateral for loans - we even have banks specializing in this.
Oh, and the US has a law that erases the tax bill for dead people - you'd be stupid not to use this trick.
