The smoking ban in Michigan bars is another example of dictatorial government imposing laws when the free market could have created wealth out of the issue.
Rather than encouraging non smokers to open bars of their own, government dictates that all must exclude smokers.
A very popular bar at one of the beaches in Delaware had gone no-smoking long before they put in the smoking ban. The owner fought that ban as hard as the owners who wanted to keep allowing smoking because such a ban would destroy the niche he had made for himself. His booming business went down the tubes. It was a shame. On the other hand, another owner claimed he knew his customers would prefer smoke free, but he was afraid he would lose too much business if he went that way when others didn't have to. I rubbed my hands in glee when he went out of business.
