Agreed on the first sentence, not necessarily on the second though. Really, listen to that podcast. A mid-grade grappler can get cash sponsorships by community involvement. Your local Coca-cola/Pepsi distributor might give some cash if they hear you're speaking at schools about an alternative to drugs and so on. If you win mundials, they'll never hear about you, but if you're keeping little Timmy off drugs, they can get all over that.
