I've seen this happening in some countries, the result was the disappearance of the middle class: the minimum wage was pushed up until it got close to the median, now people are closer and closer to the minimum wage. Imagine minimum wage is 50 units and median is 100, if you grow minimum to 70-80, but you cannot increase the median (because the market does not support all the raises), then the former middle class is now close to lower class; as you increase the minimum wage, this creates inflation and makes purchasing power of the middle class even lower, so in the end you get it transformed in an upper poor class.
