This is something like a rant or a pitting. But also, it is a request for factual answers.
I was watching The American Experience, Streamliners. In the 1940-something, the fastest trains in the world were American. Now the US is on the edge of a financial meltdown. Big American companies are collapsing, being nationalized or sold to foreign companies.
Hell, we cannot even get a memorial built in New York City.
What, if anything, does the US still lead the world in?
