Do you ask SONY why their TV's are so expensive or do you just shop for a TV that fits your budget? No difference here.

Yes, it's a business. I can tell you from experience that it's a tremendous amount of work to actually run a club. What parents see is only the surface. Like any business, there's a lot to be done behind the scenes. Finding field space, uniform design and ordering, emails, rosters, phone calls, waivers, tournament registrations, hotel reservations. It all adds up to a significant amount of time. So yes, a salary is warranted.
