It appears the sports industry in US skewed local preferences toward hardware-intensive sports, that sell lots of gear. Poor children can start playing soccer stuffing crumpled paper in plastic bags to create a makeshift ball, and using spaced sandals as makeshift goalposts. Minimal hardware requirements. It's harder to play baseball or football without all assortment of costly bats, helmets, gloves, et cetera. Basketball comes closer to soccer in this regard.
