Anything more than 40 hours is wasted life. You're not going to be rewarded for it. If they're cheap enough to not hire labor, they're going to underpay you for 40 hours of work. It's different if they give you some kind of real ownership stake in the company. Your employment at the company is only partially due to how good you are. If management blows the company up, well, it was all wasted. You (and arguably the company) are better off spending your 40 hours being as productive as possible, and using the rest of the time enjoying your evenings, family, books, tv shows, whatever, and recharge until the next day.
