Not sure how we are defining wealth here, but for 99% of Americans this is a non-issue given the estate tax exemption of $12m/individual $24m/couples. Perpetual trusts are a boon to the super rich, but doesn’t change the math for everyone else.
This kind of thing is a large part of why there is a housing crisis. The existence of this wealth is an existential threat to the middle class.
my point is that these trusts are specifically structure to prevent decendents from exiting their wealth. through poor risk taking, ineptitude, getting sued. nothing will affect the trust
+ trust fees / poor management
