That's true if the goal is purely money. I think, though, that if you're just looking to make six figures and don't quite care if it's 150k or 500k then working at a Google or Facebook will be the far better alternative as the workplace culture is better and the hours are likely to be better. For a lot of (most?) engineers, there's not enough money in the world to offset the difference in utility from working at a finance company instead of a development/research company. It's your life after all, and you spend a sizeble chunk of every day at work either way.
