Should laws regarding minimum wage (or the forty-hour work week) be revised?

I believe that minimum wage is just fine being $7.25 an hour. Its a decent pay for hours that are 25+. Also its good for people who are still in school and need money when their parents are not providing them with allowances. That goes for people who are 16+ who are ready to make their own money. Work is work the more hours you put in the higher the paycheck.... No I do not think it should be revised.
