I think that statement may be wrong, though.
If not now, at some point in the near future.
Because the other options are:
- You exist and cannot or will not support yourself, so you die.
- You exist and cannot or will not support yourself, so you must rely on charity, which is subject to the vagaries of donations.
In the former case, most people aren't OK with people dying because no one helped them (if they hear about it, that is).
In the latter case, charity clearly isn't providing enough support, since we still have people who are homeless (I'm not counting those who WANT to be homeless).
Because of this, it seems likely to me that at some point in the next decade or two we'll have at minimum multiple states that provide some form of support similar to what the OP describes, and possibly even a federal-level system for same.
