I recall some wealthy person, Bill Gates perhaps, saying he would leave his kids enough to do anything, but not enough to do nothing. That makes a lot of sense.
I think an annuity/administered trust of some sort that gives the descendants a specific amount yearly, perhaps increasing with age and presumed maturity, would be my choice - if, in fact, I had either money or kids. My cats are my sole heirs. They better not blow it all on catnip and Temptations.
