As a boss nothing angers you more then paying someone 7-10k a month on top of all the taxes and costs and watching them bitch and complain about coming to the office and commit nothing until the "feel like it" under the guise of "programming happens when it happens". This is real money and it is painful to raise it and just give it away. The developer doesn't have to answer to the angry investors and have their reputation ruined forever when the company fails. They get to skate off and go work at Facebook with valuable "startup experience" under their belt.
The reality is that 99% of programmers have bad attitudes and if you find the gem that actually pulls the cart with you, hold on to that unicorn with every ounce of your being.
