I'd say probably not as much as most people would think. It is not as easy as opening the gates and collecting the money and putting it in the bank. Besides the race night expenses of purse and payroll, insurance takes a big bite (when I was involved at Moc-A-Tek back in the early 80's, the insurance bill was around $1,200 per night, I would assume that number is much higher these days), along with repairs and fuel for all of the equipment adds up quickly. While I'm sure that there are some who are making some decent money, I highly doubt that anyone is getting rich in the racing game these days.
