I don't, not for "caring" owners. Just say no.
Racing used to be considered sport, now it's considered business, no escaping that.
Anybody who gets into it (and I hope to, to a greater extent over the next 10 years) simply has to decide where they stand regarding such issues ... how much money are you prepared to lose by owning race horses? How long will you last in the sport at that rate of loss?
I think one key to betterment of racing
for the horses, lays in involving people with less money in the sport, through fun, racing partnerships - not prospectus-laden, low-cost "investment" deals.
If my current racing stable, consisting of three tail hairs on a filly named Sumwonlovesyou

, goes belly up, I'm out nothing, I'm still in the sport, and there is no overriding financial incentive for me to do anything not in the best interests of the horse, all the time.
Not true if I have the attitude that the money I have invested is not disposable.
Successful people, who have made millions at their business, and who now get into the horse business, fully expect this business to be profitable for them, too.
Surprise! Racing is still a sport!
