No, I never claimed that. The claim that I wanted to make is the one that sublinear made: the market provides what the people care enough about that they are willing to pay for.
Eg Germany has good pork and decent chocolate in mainstream supermarkets. But the boil-in-bag rice those places sell would make your average Asian through up a little.
Consumer regulation does the least harm, when it is the least necessary: when the mainstream consumer already agrees with it, and when it's reasonably easy for knowledgeable people with different tastes to side-step.
Eg the German 'Reinheitsgebot' purity law has some strict rules about what you can put in your beer and still call it 'Bier'. But it doesn't actually restrict the knowledgeable consumer: your supplier can concoct whatever they feel like, they might just have to get creative with the name.
If Americans like 'shitty food', that's up to them. Who are we to judge them?
