Let me quote from my own comment:
> What's particularly gross about this is that many asets in many countries can be inherited by children on what's called a stepped up basis, meaning the base value for determining any capital gains taxes resets to the current market value when the owner dies. This is a massive tax break for the wealthy.
Right, I read your comment. You still clearly state that this is a loophole and when you then follow up to say "particularly gross" the clear implication is that it's a "gross loophole".
The ability to borrow against an asset is not a loophole.
