Most employees are likely taking a lot more risk than founders. In the worst case, a founder has to look for another job (same as the employee), but with experience at being an executive at a company. Lots of founders won't have to look for another job even if their company fails in the worst way.
An employee, on the other hand, puts 100% of their eggs in your basket. If the company fails then they have no income at all, through no fault of their own. What goes on their resume? "I was a grunt at some company you never heard of and never will because it doesn't exist anymore".
Granted, it's possible a founder could be putting up a lot of their own money and end up being broke if it fails, but I think in today's world of seed funding and so on, I'd call such a person an idiot. :)
