Stupid question
Well......ummmm....If you want to raise minimum wage over $7.25....why not raise it to $100?
Because $7.26 is the same as $100
The question has a very important purpose, and that is to illustrate the reality that raising the MW DOES have an impact on jobs. The degree of that impact varies with the size of the increase.
Obviously, you cannot raise the MW overnight to $100/hr and expect to eliminate poverty because no companies would be paying anyone that much. Thus, you cannot simply and arbitrarily raise the MW significantly and quickly with no negative ramifications. Go from $7.25 to $8.50 and you probably wouldn't see much right away. Go from $7.25 to $15, however, and you will have a much greater negative impact.
Raising the MW by a large amount and quickly as a tool to combat poverty is a losing proposition because companies do not operate in a fantasy vacuum, they operate in the real world where you can't pay workers more than their labor is worth and stay in business.
