The reason you are calling it shit is because you were brainwashed that it is. Up until the 80s you could hardly walk into an office public or private and there weren't public ashtrays around. Have cancer, lung, and heart disease decreased? They have INCREASED!!

Have work accidents lethal and disabling injuries decreased? No, they have increased because of unions being faught against like enemies of the state (which they are to any capitalist state).
