Americans tend to think about themselves as informal/loose, but they evolved to be very formal and structural, in reality. Tend to like a lot of formal rules about everything.

If you look at Latin American movies, they themselves are different then American movies and show different culture. They are not the exact copy of their cultures of original, but they certainly show quite different social behavior and values.

It's similar to how they schedule all the free time of their kids too. Or their own free time for that matter. Must spend every minute being productive, every minute counted towards some labeled activity. Everything that isn't classified as one of these things has to be cut out, minimized, made more efficient etc.

I would amend to: what Americans don't like to accept are what they see as preventable mistakes. The least American sentiment of all is "shit happens". Americans sometimes say that, but they don't mean it. What they really mean: "this shit shouldn't be allowed to happen". Hence the rules, and (in the extreme) the litigiousness.
