The best limit for something like this would be to just move to hourly pay. If people were paid for each hour worked, it would be self limiting. I've heard that in some countries, such as France, they actually post police outside of office parks to arrest people who work "too many hours". Makes it hard to start a business when you're limited in how much sweat equity you can put into it. And I'm sure police have better things to do than to prevent people working.
