> Another thing is that the us and European countries build their wealth where they had los standards now other countries want to do the same but would be limited by us and European countries. It's very tricky

No, why would you say that? When America and Europe built their wealth, they were mainly (though not exclusively) producing and selling manufactured goods for themselves. This whole idea of a poor country developing by building polluting factories to make items for rich countries is a more recent and different thing.

Europe and America insisting on certain labor and environmental standards as a condition of trade wouldn't mean poor countries can't build factories for themselves. At worst, you just split the current one big market into two smaller markets: an expensive and clean one, and a dirty and cheap one.

Is it actually tricky?

Do we let other countries wage war, pillage, etc. because others gathered wealth that way previously?
