Why should the government dictate how a business is run.
They interfere enough with other regulations and paperwork.
Vacation is a benefit that the company provides to the employee
because low vacation time and dishumane working hours create damage to all society through medical expense and lost work-time.
Holidays is a necessary interfence in business just like forbidding child labor is.
@HeXen, some people just don't know what to do with their vacations and that's fine, but it's a fact that you are part of a minority and that most people do get stressed out at work and need a period of time longer than a week-end to disconnect from it.
Also for families holidays are absolutely necessary, hayabusa is right on. During normal weeks they see their teacher more than their parents.
Anyway your problem is maybe that you're trying the wrong kinds of vacation.
Trips should be about discovering different cultures, food, cities, architecture, cool buildings and landscapes. If you're a very physical guy you could also do rough like backpacking etc., something that is not so easy.
If you just don't care about this stuff, you can always use the time off to do some hands-on hobby you like.
