For me it is not the horses which present the problems - it is the humans.
Some lie, some conceal the truth. Some should never be left alone with any horse. I would find watching a horse being driven off by some perfect stranger very distressing.
I earned my living as an international trader but I have no regrets that I never bought a horse with the idea of selling it for profit. I never mixed business with pleasure.
Anyway, there's no money in it until the economy picks up - either in the US or in Europe. Those bankers and economists have to get their act together first.
