Honestly what USAC does with it's sanction money is USAC's business, A race is run, it's purse posted. Racers have the choice to show up and race for it or not.

What I was saying, Is that without them leasing a track and holding a race at several venues. There would have been no race in the first place for teams to run

If indeed USAC is leasing the whole works, then they've found a way to make a profit off other sanctions and non sanctions. Been my experience the biggest crowd at Bloomington isn't for USAC or MSCS but for it's fireworks race.
The only way to put more $$ in the racers pockets is if your willing to pay more. USAC's sanction fee isn't outrageous for tracks
