Nothing. The world is as it is. I've come to accept that.
But -- here's the thing -- your moral/ethical compass shouldn't be influenced on account of the world. Think back through history, and at every point, people have been essentially crazy. So the only thing we can do is to have the confidence to know "what's good", and then strive to make our personal lives reflect that. (Without becoming judgmental of others. </irony>)
If you're asking what I'm going to do about it, well... I'm just like everyone else. I train myself for years in every aspect of game development, am building an entire multiplayer game from start to finish without relying on anything except my creativity and capabilities, and will be done around age 39. :) Then I'll use the proceeds to form a company and hire a few likeminded people.
