Depends on the "level" that your kid plays.
If you have ambitions for him, and of course have $$$$$ . . . you will sooner or later get swept up in the "Youth League" system. It's a higher level of competition, generally better coached and better players competing in it. But full of politics and agendas.
And then on the other hand . . . it costs you maybe 3k per year, a lot of clubs have massive agendas as to who plays and who rides the pine. For example, your religion, your ethnic background, if you drive a top level Land Rover, if your Mrs has had the girls done, if the coach fancies himself with your Mrs or her new girls, and of course if there's any spots left in the team after all the sponsor's nephews have been picked.
This 3k payment inevitably is to pay the senior players of that club, though you will be told it's for the development of your little Messi.
Generally, after 5 odd years of 3k p/a, your kid will be either sick of sport, be too involved with school/girls/other distractions, or just wants to go back to Park soccer and play with his mates.
