"Many parents in the United States assume that (math ability)
is just some kind of aptitude -
some kids have it, some kids don't . . .
The result is most of our kids (in the U.S.) don't do really
well in Math . . ."

Becoming good at something most of the time requires support, instruction and encouragement from others. First of all, we need instruction from experts, and second, because we need encouragement in the beginning when practice is mostly about making mistakes and correcting them. Parents and teachers know this well and use positive reinforcement all the time (sometimes even too much).
