What do low wages cost us?

Google: public cost of low wages. 
Saw this article and am really curious to hear what others think. I keep hearing arguments against raising minimum wage, but from this data it would appear the public is just supplementing the current low wage while large businesses pocket the difference.
Thoughts?
