It looks to me that the biggest concern to raising the minimum wage is a resulting inflationary offset that negates the income increase and hurts those on a fixed income.

As I and others that are way smarter than I am have pointed out is that stagnant wages don't slow down inflation. When a business raises it's prices year after year but pays their employees the same minimum wage they make more money. This goes on for at least a decade between raising the minimum wage.

The difference between the lowest paid worker and the highest paid employee/owner has grown substantially over the last 70 years when looking at an earlier example I gave. Capitalism is great but there may come a time when the 99% refuses to play the game anymore.

I once saw a picture of a bunch of rich white guys playing a game of monopoly. The table the game was being played on was held up on the backs of black guys on their knees. The caption on the picture read "all we have to do is stand up".

The rich need to remember that the money and power they have can be taken away. Play the game with some compassion for the people or the game ends.
