Most of the founders I deal with pay their employees before the founders themselves get a dime of salary. Sure the founders get the bulk of the equity. But they also give their employees equity awards, even though the employees get paid a salary, as well (i.e. they don't take on the same risk).
In comparison, in generic corporate America, the people on top get substantially more guaranteed cash compensation, in addition to any stock awards.
In addition, I've had plenty of startup clients who did all sorts of generous things for their employees that were not required. For example, when getting acquired, I have had clients give special cash bonuses to employees to ensure they get a sufficient "upside" in the transaction (beyond what the employee was entitled to from their stock or options). I just haven't seen that type of behavior in more "mature" corporations.
