Increase in food, restuarants, hotels, etc.
It is believed that 1.7 million americans earn $5.15 an hour. These people tend to word in fast food, hotels/motels, other restuarants, gorciery stores, wharehouse, pizza devliery and other low paying industries.
Look at what you are paying now and what you will pay after the wage increase and you will see the price of hotels, rental cars, and pizza go up.
Now people who are earning better than minimun wage won't have to modify their life because of these increases. However, the people the wage is suppose to help will have their new earning eating up by the increase in grocieries, fast food, healthcare, and other goods and services.
Seems to me the better answer for peole earnign low wages would be to work more hours, not a wage increase that is going to increase the price of living.
