I will probably get spanked for this, but in my opinion raising the minimum wage only pulls the middle class down. Today the bottom is $7.25 /hour and if the bottom goes up to $15.00/hour then prices and the cost of living will rise to meet that new purchasing power. The rich will still be on top as more of us slide to the bottom of the pile.
I think we need to get young folks to take the long view, stay in school, get an education and aim for a higher calling in life. When the pool of unskilled labor begins to shrink then the Walmarts of the world will begin to pay higher wages.
I'm done rambling and ranting for now.
