The minimum wage argument is one of the easiest to debate.....
Someone in here mentioned Walter Williams, who has a great article on the minimum wage.
Peter Schiff has also brought up excellent points on it as well.
1. Why don't fast food places have real silverware? Perhaps because at $7.25/hour it's not worth it to hire extra dishwashers, but maybe at $5/hour it is. What happens to all the kids who don't have any job experience yet and want to earn some while gaining some extra cash? How are the poor supposed to get richer if they can't find a job to push them up the economic ladder?
2. It causes huge amounts of unemployment... minimum wage hike in the mid 90's

Economists have studied the job-destroying features of a higher minimum wage. Estimates of the job losses of raising the minimum wage from $4.25 to $5.15 have ranged from 625,000 to 100,000 lost jobs. It is important to recognize that the jobs lost are mainly entry-level jobs. By destroying entry-level jobs, a higher minimum wage harms the lifetime earnings prospects of low-skilled workers.
minimum wage hike a couple years ago...

Increasing the minimum wage was meant to raise the living standards of millions of Americans holding unskilled, entry level positions. But it may have led to the elimination of 550,000 jobs -- opening the possibility that such wage levels should be revised, suggests a new study from Ball State University.
Who are the people who get fired first? The poorest, the least qualified, the least experienced....statistically minorities, very young and very old, and the poorest.
3. The higher wages is just increased costs for businesses which pass on most of those costs to the consumers, who in this case are the poor, because the lowest paying jobs are in fast food, grocery stores, etc, where consumers are much poorer.
4. It destroys wealth. Wealth is someone's value on an item. Trading increases wealth. Hiring an employee increases wealth because both the employer and employee are better off afterwards otherwise they wouldn't have done it. By prohibiting hiring people under a certain rate, you destroy all wealth that would have been created.
5. Even to the employees minimum wage laws do help, the amount of help is extremely deceiving. If the employer is forced to pay a hire wage, they will simply decrease benefits and/or hours given to the employee. So even the winners (employees not fired over wage increases) are not necessarily winners either.
6. Barring an employer from hiring an employee at a mutually agreed wage is an attack on the freedom of association. If we don't have the freedom to associate with eachother, what freedom we have left? None.
That's about it off the top of my head....the points aren't in any order either, they're sort of all scrambled. If any of you ever get the chance to debate some dumbass on this issue feel free to use any of these points, because they can't be refuted.
