Startup People are just people like everybody else, though, somehow trying to get by. It is not like most of them are swimming in money, trying to be successful just for fun. So why should they have a special responsibility?

I am not against solving the worlds problems, but I suspect it makes more sense to focus on the problems you also have a chance of solving.

And I buy into the "to create wealth, create value" mantra (or what is it exactly). Anyway, I think if somebody is successful with their startup, they probably have build something that people want, and hence made the world a better place. Even if it is just a game or some stupid network, I think it is still valid and valuable. If the starving people get their first computer, they'll want to have something to play, too.

If the only goal would be survival for everyone (without any prospects of fun), I would probably look into deep freezing technologies.

Finally, I would like the challenging blogger what he himself is doing about those problems?
