To play the technical style you described, boys worldwide spend 10+ hours each week mastering their craft. We tell our girls to focus on academics (and rightfully so) and most train perhaps 3 to 5 hours a week. Without the necessary investment in time, the "American Way" might be the optimal strategy for girls.
In other countries kids are tracked and sorted into the various university, sports, arts and trades. The US is one of the few countries that tries for college for everyone. So it makes sense for the European boy on the academy track to spend 10+ hours a week master his craft. And for our girls to focus on academics needed for college.
