A driver's win portion in a $20k purse race is only $500. If he is on the fav and is off the board it isn't hard to make more than that even with a light trifecta pool. Just think how easy it would be to make more than you'd earn in a 6k -8k race. Now, I'm not saying it would be anywhere worth the risk of throwing your career away, but there is money to be made.
