Five years of experience as a programmer is like becoming a "made man" in a crime family. Before, you're nothing. After, you're trusted and respected.

I was in the same job from years 2-5 and didn't see much of a raise. Then when I got a new job it was more than double the salary. And it does seem like you have to leave to go somewhere else, or else you're a prophet without honor.

It's also clear from the graph that after 5-10 years of experience, much of the increase in income growth will be expected to come from non-salary compensation. Which may be equity, bonuses or stock plans, but it's all about getting a piece of the action. Which, again, makes programming sound like it's the mob. Sorry about that.
