Why is food better in poorer regions

Firstly, do yous agree that this is true?

I find it a very general rule, in Europe anyway, the poorer the area the better the food.

And if so, why?

My theory is that it relates to industrialisation. Developed countries, they are developed because their cultures are focused on efficiency. They are endlessly searching for ways to do things more cheaply.

So you find farms, distributers, shops and restaurants, all trying to minimise their costs quite aggressively. They are not interested in quality. They have no pride in their work.

Poor countries are poor because the focus too much on quality and not enough on finding the cheapest possible way to do things.

Does this explanation extend to other cultural elements apart from food?
