You've got a point but still, breed clubs (at least in Holland and Germany) are controlled by their members. They get to vote on any descision made. So in the end, it IS the breeders too.

I always feel al lot of the bad stuff profit related

Short fat labs without ant energie fit in almost any family without a problem, where as a working line lab (they do excist and I LOVE those!) would cause trouble if not handled properly, so which one is easier to sell?
We have been changing things too, as members of the club. It actually happens too, even if the club board would not agree, but a mojority of the members want something, they have to make that change.
On GSD, I used to train at a combined SV and ADRK (rottweiler) club, so saw a lot of GSD and their breeders there. I remember very well, one day I was looking at this GSD male, doing well in sport, and all I could see were his hindlegs shaking all the time, see this weird way of walking, back sloped like a slide

As I was thinking this, his owner, stepped up to me (he had someone "do" his training for him so he could sit and drink beer ) and he said "nice dog eh, you do not look at physiques do you, but this dog has the most stunning physique ever!" I was going to say stuff, but decided it would be better to just keep my mouth shut. These people do not listen at all...
But yes, I DO pay attention to physique, and this dog can barely walk, will win every show and breed like mad because he has "KK1" (highest level of conformation), and SCHH3, and he will have loads of offspring, and will die at about 7 years old because he can no longer move, is in pain, and starts to act up towards his fabulous owner

All his offspring will live the same great life, and they all love this breed SO much...
They actually call a dog that has HD at the age of 9 months "broken". Not ill, or hurt, no, it's broken. So they will be dumped in a nice family home(in the best case), so they get to pay the vet in the years to come... great.
Moral of the story: the SV is their club, these people decide, it is in their mind too, this sick physique. I feel you cannot just say it's a club's fault and the breeders are forced in this direction, that's nonsens, if they all do not want this, they will not.

There are still breeders who do NOT breed these sloped-back dogs.
