Well the fact that the current minimum wage is lower than the living wage in almost all US counties is a pretty good reason to raise it. forcing companies like walmart to pay a living wage is a good thing considering how many employees they have and just how much they hate giving those employees a fair salary.
Just because WalMart is the devil doesn't mean their wages should be regulated any differently than any other employers. Obviously a small business owner is going to have a harder time paying their employees more, but it shouldn't matter.
The only people who would want an increase in minimum wage are the workers who are being paid the current minimum wage now. According to the Bureau of Labor Statistics, of the 73.9 million American hourly-paid workers, 1.7 million earned exactly the prevailing Federal minimum wage of $7.25 per hour and about 2.2 million had wages below the minimum. Together, these 3.8 million workers with wages at or below the Federal minimum made up 5.2 percent of all hourly-paid workers.
Only 5.2 percent of the work force. Why should we care about only a small percent?
First off, there may be only a small percentage of people working for minimum wage, but there is a much larger percentage of people working for slightly above minimum wage. If the starting point is (let's say) $7.25, then $10/hr sounds like a lot, right? But it's still next to nothing. The minimum wage is still a guide by which employers will decide to pay their "non-minimum wage" employees. If the minimum wage was $10 instead of $7.25, then the people that are currently making $10, would be making (i dunno) $12... and so on and so forth.
