It turns out that while these are all truisms, nobody wants to fix them. Developed countries are okay passing pigovian taxes, to a limited extent, to help fix these problems. Developing countries are even less interested in fixing these problems. It turns out that austerity is incredibly unpopular. Everyone wants to tell other people not to do the things they don't like but nobody wants to listen to what other people tell them not to do.
Just a reminder that Europe colonized Asia, Africa, and the Americas in the search for spices. Later on the interest changed to tea. Literally the only thing that Europe wanted was better tasting food and drink (initially at least.) By the time the potato had become widespread, they could have had enough calories to feed the continent, and yet the desire for flavor is what lead to untold misery for hundreds of years for millions of people.
We need to be realistic about what works and what doesn't. Austerity never wins.
