Harkin on Minimum Wage

In this editorial from USA Today, Sen. Tom Harkin argues that the Federal government should increase the minimum wage to something higher than $9 per hour, the current proposal. Here are some quotes two paragraphs near the end of the editorial.

• Raising the minimum wage is one of the simplest and most effective ways to help working families succeed.
• Contrary to publicized myths, research proves that increasing the minimum wage will not cost us jobs; in fact, our proposal would create at least 100,000 jobs through increased consumer spending.

An argument against a higher minimum wage is doomed to failure if his statements are correct. According to Harkin, a higher minimum wage helps "working families succeed" and creates jobs. His statements lead me to wonder whether he would support raising the minimum wage to $100 or $1,000; why not really help working families and create many more jobs?
