I would proffer that kids that play HS lax, volleyball, soccer come from higher socioeconomic classes than other sports. In my experience, families with kids in these sports look for sports participation to get their kids into better schools than they would have otherwise. They are willing to pay most or all of the tuition. Foe example, I have a friend whose daughter was recruited as a non-scholarship field hockey player to a top 25 school. She received admission into that school because of field hockey. She would have struggled to get in as a non-athlete.
