BRIC countries have many of the same problems the US has for the same reason—massive financial and moral corruption of the elites.
Their is corruption in every country. I don’t think that will be an issue.
A big part of the reason why these countries are so successfully besides the rigged trade deals are the low taxes in their countries. We have some of the highest taxes in the world. In addition, they have tariffs which makes it hard for us to export to them. While it’s cheap for them to export to us.
