Outside of the "how to pay for it" question (which has never been addressed beyond vague "tax the rich" promises) there's another problem: how to save people from themselves. One could think of this as an annuity, and try to cash it in for total cash value today (e.g. lump sum payment): get $200k today, and sign over the rest of the checks you get for life. Then what do you do with bankrupt folks? Sorry, you had your chance, now you starve in the streets? Of course not -- so you still need another safety net for those people.
