It was great 50-30 years ago, and now we're doing a really patchwork job at maintaining it, basically. The prototypical example of poor US infrastructure is the Detroit water system, which is literally filled with lead and is poisoning people, but they refuse to set aside the money to do anything about it.

But the federal government is more than happy to send aid to Venezuela because it fulfills their political goals. But meanwhile in their own country Detroit is left to decay and rot. The hypocrisy is very upsetting to many Americans, especially since it's basically theft of our tax dollars!
