The financial industry is a necessary evil because our entire financial system is so fucked up. I recognise that a certain amount of cognitive dissonance is required if you work in the industry, but I think saying it is a primary driver for social improvement is really taking that way too far.

That said, if you write cool software that is cool. It doesn't need to have a huge social impact as long as you enjoy creating it, which appears to be the case here :)
