Never was minimum wage equivalent to a living wage. A living wage is an ill-defined term. Does it mean I can afford the smallest apartment and afford just enough food to survive or are we adding small luxuries to this?
None of the Nordic countries have a minimum wage --on the other hand they don't have a large undercurrent of illegal labor undercutting the minimum natives will accept as a minimum wage.
That said, I don't have a horse in this fight. I don't think business have a "right" to cheap labor and if they can't survive without it, then so be it. Of course people have to understand their services and goods will go up in price and they should be okay with that. Maybe they stop depending on someone else doing and making things for them and start making their own stuff at home.
