Totally agree with this. Until the U.S. have as many horses as you have in Germany, horses in the U.S will always be more expensive.
I guess I should speak up. OP, I myself have imported 6 horses from Germany for the exact reasons you mentioned. I might get some flack for it but my last import was in 2007 ( I think by now the U.S. has more stock to choose from) but also, it was because I found that in Germany, where Hanoverians are in abundance in concentrated areas, you can go to one place without having to spend thousands in air fare, choose what you want and get it to your farm for roughly the same price as one you'd find in the U.S. The mare I have now, would have cost me much more to buy in the U.S. She is everything an American breeder or competitive rider could ask for but in Germany, her kind is a dime a dozen. IF I could find one like her in the U.S. and of course, they do exist, I would be hard pressed to get a breeder to part with her AND if she was available for sale, would be totally unaffordable. I bought her from their door to mine, she was a green broke 3 year old, so I could try her under saddle, for what I've seen some yearlings go for here in the U.S. I do understand where you're coming from
