I am actually advacating for something different: I am not taking your money, I am saying after some level, what you accumulate is not - your kids - money. It realigns incentives (do something with it before you die), helps your kids (unearned weath corrupts, enormous unearned wealth corrupts enormously), and actually enables opportunities through investment and redistribution at a time when most people need something like a downpayment or school debt clearing.
