To be honest, I don't know what a horsemen's group can do to grow the sport and handle. For all the people who advocate a huge and expensive marketing campaign, they need to rethink that. Advertising a product that is unappealing is ridiculous.
Giving up 5% of the purse account to do this is foolish. Giving up 5% of purse account to better police the current product is a solid investment. Once you can up with a program that builds confidence and trust in your current fans and gamblers, you can then advertise for more market share.
I have some thoughts on such a program.
