I agree with KYS to a degree. It is not all the breeders or indeed the showing concept that is at fault. It is the people who set the breed standards and the judges that award the dogs with the most exaggeration of a point that need to change. This is how "normal" pedigree dogs have ended up with breathing, whelping and movement problems. The breeders are only trying to conform to an often ridiculous standards set by people who should, frankly, know better.
