It comes down to governments and societies.
[QUOTE=Tiny12;435045]Esten, Black Shirt and WT69, Singapore spends 4.5% and people live longer:[/QUOTE]As you know, Singapore has been under 1-party rule since independence. So you can say that Singapore have an authoritarian government, albeit elected within democratic guidelines. Fortunately, it is under "good governance" because the elected government is honest, dedicated, innovative, and planning within a very big picture. Social engineering is very vital to its core everyday message as well as in its long term planning. In other word, Big Brother is not only behind you, but all around you. Not really a problem for industrious, family oriented, law abiding citizens. American society today hardly fit that description.
So, can Americans tolerate that? No way, not even if they promise that every citizen can be a millionaire if you follow the rules. You want to pack a gun. No problem, $500,000 just to obtain a license to buy. Then another $25,000 per year to renew. That's how it works there. Just google their car purchasing process. So you want to smoke pot? Ahhh, you don't want to go there.
As for their living longer, well, you figured that one out. Really, not too hard.
P.S. The gun stuff, I made it up. Just an example of how government regulates activity and everyday life.
