"Economics work against the poor kids in American soccer. Lusson sees this every week as he moves between the teenage girls team he coaches in the wealthy San Francisco enclave of Pacific Heights, and the teams he manages in lower-income Hayward. One night, a few weeks ago, he listened as girls on the Pacific Heights team talked excitedly about applications to elite east coast colleges. The next day, in Hayward, nobody talked about college.

And yet he is amazed by the skill of his Hayward players, who he says would crush the Pacific Heights team in a match. These are the players who could be the future of American soccer, perhaps even rising as high as a national team. But he also knows that the Pacific Heights players will be the ones to play on their college teams and will be identified by US Soccer. They are the ones who will get a chance that the Hayward kids won’t. And this strikes Lusson as very wrong."
