Actually he could care less how much people make an hour because grocery stores are all just going to pass on the increases to their customers. They aren't all of a sudden going to turn into a non profit company. 

He is merrily pointing out that there is cause and effect to the increase. People with money don't care about the extra few cents things will cost, but those with less will notice the increase much more. 

conveneiently the government will also get 20% of the increase as well, so your $3 increase is really $2.40 and the cost of everything from your timis to your gas to your big Mack is all going to increase. It's a living wage until the new economic reality kicks in.

Add to all this that jobs will disappear and the reality is they have just made things worse. 

They will get some votes at the expense of those they are using as pawns to get re elected. Congrats.
