A place to start (USA chapter) .

Sadly, applies only to perhaps 20% of world population, those without food problems (and with some time to spare). And how many Americans have first to get off food stamps before contemplating advantages of "slow" vs. fast food?

As for taxes (i.e. more openly introducing import bariers): OK, but we will first have to dismantle WTO. I am not entirely sure what to think about more and more popular idea of returning to closed economies. I have impression that most supporters didn't think the consequences out.
