I don’t know, natural resources are also abundant in Canada or Australia? I think a combination of high salaries and constant influx of highly talented and competitive immigrants (to study at U.S. universities) from other countries is a natural contributor to U.S. economic and intellectual strength. The students who come to study here end up staying to work, which works out well for companies looking for highly skilled workers. That all said, if you’re not a certain type of immigrant or worker, living in the U.S. is super hard and economically trying—increasing equity is something that all countries should attempt to resolve.
