gavra, no one “expects to live off of Tzedaka”; you think the poor who come collecting for food or to marry off their children (hachnossos kallah is a tremendous mitzvah itself on top of tzedaka) WANT to embarass themselves by begging? They unfortunately are in that position. Hashem makes sure every generation has its poor, so the non-poor can have the tremendous zechus of supporting the poor.
Would you like to trade places with them? You beg and they will give you tzedaka??
