How much empirical data do you need to convince yourself that jumping out of a window with an umbrella is unsafe? Everybody can understand that employing people at a loss is unsustainable and that the goal of employers is to make a profit. I think there's plenty of empirical data for that, the rest just follows logically. Of course there's bound to be a narrow range where you can move some profits into wages and you have neither rising prices nor unemployment, but that number is going to be different for every location, every sector and every business. I wouldn't trust politicians to come up with a magic number here.
