Another related aspect to consider is that it's really not very hard for the wealthy to create an inheritance-like legal vehicle even without special cases like trusts. Should it be legal to contract with someone that you will give them $1B now, and they will provide each of your descendants at least $X/year (or guaranteed job, housing, etc.) for the next 50 years? If this kind of contract remains legal — and I don't see how you could make it illegal without stomping on a lot of contract principles — then the only thing we're really changing is the timing and quantity of taxation. Allowing inheritance makes intergenerational economic development possible for far more than the ultra-rich (who could already do it anyway). That doesn't mean taxation policy shouldn't be considered, of course.
