> that the very rich can create schemes for multigenerational transfer of wealth without ever paying tax

Also important to note that the major financial institutions are complicit in these schemes because of the financial upside they get out of it even in a limited number of transactions, due to the large amounts of money involved.

One wonders if in today's digital self-serve world, a retail bank could implement a version of this scheme that is totally self-serve (and therefore super low margin) and make it accessible to everyone.

I suspect if that happened, the rules would be changed quickly.
