A self realized person sees things as it is. He knows very well that while eating, sleeping,walking,evacuating&moving about, only the material energy is in action&he is simply an observer only making the choice of desiring different things. If we deserve, we get what we desire. So first we have deserve defore we desire.

The more we desire to Lord over the material nature,the more the sufferings that are imposed upon us. So when we are suffering too much physically&mentally, it means we have undergone too much Sense enjoyment in the past.
A sudra is never satisfied by whatever he obtains. So when you give him more than what he deserves,it spoils him even more because he engages the excess he obtains in Sense enjoyment. One example here is the rickshaw drivers who misuses the extra money you give in drinking or smoking,so this is not the place to apply our compassion. If we can give the excess wealth to qualified Brahmana,he doesnt misuse because he knows the problem in Sense enjoyment&he utilizes everything for the good of the whole society by performing sacrifices for the Supreme Lord. But unfortunately,today the whole society is lead by degraded men who are actually sudras but have undertaken the administration&therefore they dont know what's good for their self as well as for the public.
Therefore the whole society is ruined now.

Use Compassion at the right place!
