2 reasons it won't happen:

1) Too many big donors and Democrat supporters in the wealthy Democrat enclaves of CA and NY that have most of the nation's 1%ers. The party of the rich (Democrats) won't risk biting the hand that feeds it: too easy to just kick it down the road for the next generation, yet again.

2) Too many billionaires already have property tied up in perpetual trusts and other pseudo-person entities. Wealthy kids who already are beneficiaries, never actually inherit anything. Nobody need ever inherit again.

>> Anyone with eyes can see that there is enormous waste in the government system.
>> I'd be hammering away at military spending, abuse and fraud in Medicare (some estimates are 10%) and other stupidities in the federal system.

Be careful of the fraud allegations: there will be a few high profile crooks stealing some $M, but along the way the specter of means testing Medicare inevitably will be raised once it becomes clear how many wealthy people have their healthcare paid by today's overburdened taxpayers who, as you note, aren't left enough to buy homes for their own families. That's not very fair, so why not means test? People overflowing with valuable properties and other assets really shouldn't expect recent Hispanic immigrants to pay the healthcare bills, especially when the Hispanics' parents don't get Medicare. How is that fair?
