This is a strawman. Clearly mhartl is doing something good for society. If his goal in helping society is so that he can build a pool of money he can dive into like Scrooge McDuck, why do you care? Is helping society only good if the person who does a good deed only cares for helping starving orphans and lost puppies?

The only time having self interest is wrong is if that self interest hurts society. What's wrong with furthering your own interest if society benefits in the process?
