Did I say mandatory? I meant optional! You’re “free” to die in a cardboard box under a freeway as a market capitalist scarecrow warning to the other ants so they keep showing up to make us more!
Homes are taxed based on assessed value. They are already a form of taxing unrealized gains.
Most of the population either has:
- no unrealized gains
- gains in a retirement account that we can’t borrow against
- gains in real estate that are taxed, but can be borrowed against
- a combo of 2 and 3
I think it’s fair to ask that the rich play by the same rules. You can either borrow against your gains and pay taxes on them, or not pay taxes and not be able to borrow against them.
