This is a "price control" violation of a free market. Many think of price controls as an effort to keep the price down. But, forcing the price higher via government mandate is still a price control and a distortion of a free market.
You got that right. Unfortunately, it's supported by the "bipartisan" Party of Gubmint in Wisconsin, and they have essentially all the power (the only arguable place they don't have complete control is in the Assembly Pubbie caucus, and even that has been sliding toward their way of doing things).
