Nothing aggressive. I make sure people I employ gets paid well. I give tips generously. I have taught young kids in slums and I donate my clothes and other used stuff quite generously. I don't give to beggars because it's like supporting an industry that should not exist at the first place. It really hurts to say not to these folks.

You really need to be on the ground to help these folks. There are NGOs and social organizations doing this on the ground. I think online tech space can either assist this (for example a web app for an NGO that collects clothes) or a startup that tracks/rates various NGOs and monitors their funding/spending etc.

I am no expert. My few quick thoughts.

The online tech space/startup is a tool of wealth creation, and wealth if handled conscientiously can solve a lot of problems. The way I think about it is, it gives me a chance to do very well for myself in terms of money and influence, and maybe later, I'll put this to good use to work on these problems directly.

As for direct effect of tech venture on these problems, the effect is only of a trickle-down magnitude.
