I once heard an anecdote that might describe some of what's happening. In the trenches of WWI, when it was time to fight, soldiers would have to climb up a ladder onto a battlefield. The problem was that German snipers could see the tops of the ladders. The Germans would keep their rifles fixed on where they knew the enemy would emerge and simply shoot them down once they saw helmets appear.

The European Allied soldiers were so disciplined that they just kept climbing up the ladders and getting killed one by one, following their orders to their deaths. The Americans saw this and said, "fuck that, I'm not climbing up there."

I think most Americans are pragmatic and they won't do something unless it makes sense. And to be honest, most people don't need to study math. Or at least it's not obvious that they do. I think most of the math professors I've talked to would agree. They view math, as it's taught in core curricula, more as an art than as having vocational value.
