That's particularly prevalent in most girls sports and boys lacrosse for whatever reason in my experience. But especially girls soccer. When I worked in a rich area, the girls in town were constantly playing soccer. I coached their team one year even though I hate soccer and know nothing about it, and we didn't lose a single game. My current school in the hood couldn't even get enough girls to try out to form a team. Middle and lower-class families aren't investing in those sports for whatever reason.
This is my experience as well.
I coached a travel team while my kids played premier. One year I joined with an investment banker in town, former D1 player from Brazil at Cuse, and we went over to the poor side of town to start a new club. I brought along a HS football coach whose daughters were all playing soccer on my kids' teams (by the way, ESPN did an hour long feature on this family, because they qualified for the US National wrestling team, but were not allowed to compete internationally because they wanted to be covered neck to toe in sports clothes as Muslims). We coached an all ages group (7th through 11th grade) of mostly immigrant kids from Central America, Somalia and Burma. The parents worked 3 jobs a day, and we had to take turns picking up kids at their home since the trek to the field was a 45 minute walk through the city. We packed them into cars like sardines on gameday. The HS football coach was tyrannical and ran practices like bootcamp. No lines, no stopping, when we weren't doing tactics with one group, they were moving.
Anyway, the whole experience lasted only 2 years. The kids dropped off because of the commitment and we were spent ourselves. The investment bank guy kept at it by taking the competition down a notch into a House League.
My sense was that getting poor kids from the city (even if they come from soccer culture backgrounds) to train and organize required a great deal of resources and dedication. I'm not proud to say we gave up.
