Why doesn’t the USMNT live up to its massive potential?

I’m not saying the USMNT is awful or anything, but considering it has the third-largest population in the entire world and practically infinite resources, they have wildly underperformed. The U.S. has over 330 million people, more than Argentina, France, and Italy combined. Yet, while those countries have brought home multiple World Cups, the USMNT has only made it to the round of 16.

Soccer is growing fast in popularity here, and the infrastructure for sports development is unmatched as there's more investment in sports than some countries’ GDPs. With all its advantages, the USMNT should be a superpower in world soccer, not just that team people hope "might do better this time." So why isn’t it?
