One problem with proposing policy in liberal circles is there's always the "but a different policy would better serve poor people!" argument. Sure, yes, this is always true. I am not against helping poor people, but policies can be good even if they aren't designed to help poor people.
And if you want to help poor people, the place to start is making the policies which do more directly benefit them less onerous. Fewer bureaucratic hurdles. Make them more...universal... even.
