When you raise the minimum wage, or require the employer to provide health insurance, you are closing the door on many potential employees and definitely increasing the unemployment rate.
Employees are paid according to their value. If you are making low wages it's either what you're worth, or because you're too stupid to realize you're being exploited.
I for one think people have a right to be either worthless or stupid, and therefore do not think business should be regulated in such a way.
