You know - when things go to **** people demand the government *do something!* to fix it.
And when things go to **** and stay that way for 10, 15 and 20 years - and the government does *nothing* about it then many people go 'why the **** aren't you doing anything about this problem!'
So then when the government finally decides to get concerned and involved - other people bawlk and cry 'we don't want you telling us what to do!'
So it's really just like all other issues - you can't please everyone. But in this area it's concerning peoples' health - and people's decisions will affects the government's pre-determined interests and expectations.
