Not everyone who eats unhealthy food dies, nor does not everyone who eats healthy food lives to see 100. But fundamentally looking at other people who have managed to live despite of eating unhealthy food or some combination of these isn't the way to go.

The people who have lived to see 80 despite of eating McDonalds burger everyday, have done that due to a combination of good genetics + some other redeeming qualities. This does not mean that everybody should eat McDonalds or anyone talking about harmful effects of unhealthy food should shut up because clearly there are people enjoying their lives while eating unhealthy food.

Take for instance, an African country trying same socialist policies will not see the same effect as a European country trying them. Same thing goes with Capitalist policies.

Socialism in Russia was very 'Russian', and when they got Capitalism, it's again very 'Russian' in nature. In fact when you go back to Tsar's times, you'd find the same 'Russian' entity about their culture.

Of the few truly socialist ones, the only one I wouldn't consider an outright failed state is China, and that's a can of worms unto itself.
