Do we have a duty to help the poor? How do we quantify that?

[Spooky]

OK.  Where I was actually going with this is - if we have a duty to help the poor, does that then translate into a right to that help for the poor?  In other words, does a poor person have the right to have his basic material needs met by someone else?

Offhand, I would say no, thinking of Paul (?) saying about those who do not work, do not eat.  I could be wrong.
