Are you what you earn?

Simply terrible advice. How many scammy pointy-haired-boss types haven't tried to use "we'll take care of you in the future" or "but the job is so exciting, you should be happy to work for half what you're worth" to justify low wages.

Top developers know they can get a job doing something they enjoy or care about that comes with a good salary and benefits, why should they even consider such a job as Ben is offering?

Even if a developer doesn't care about money, the compensation is a big indicator of how the company/boss views your value. If they are paying you $10/hr, do you really expect to be treated as if you are an important, valuable part of a team?
