If a potential worker doesn't like an offer,they are free to turn it down. A minimum wage may price some jobs higher than they are worth. In that case, the job is likely to be eliminated, depriving the worker of a job, and the employer of the ability to hire someone to do useful work at the lower wage. Here's the truth. Jobs do not pay what they are worth because there is no comparison between the bargaining power of an employer and an employee.
Employers usually face a labor market in which th ere is a surplus pool of labor.
They know that, if one person won't take a job because of an inadequate wage, another more desperate person will. Meanwhile, mos t workers have nothing to say about what they are paid. In the extreme, where there are no legal or social barriers to prevent it, industrial workers in third or fourth world countries may be 20 cents per hour. No on e can seriously claim that is what their labor is worth. Any job that is worth hiring someone to do, is worth paying him or her a living wage to do it.
