The philosophy is: MONEY. That is all.
Edit: Someone mentioned Australian golden/labradoodles. Australia is where they originated. I have friends who purchased one from Australia when they were "new" several years ago. My friends are, in fact, responsible dog owners and have given the dog a wonderful life. I don't understand why they did that, but at least the dog is a family member for them. About a year ago, the breeder who created them in Australia issued a public statement that he really regrets creating/promoting a "new breed" when there are so many abandoned dogs in shelters. Nice that he recognizes the problem, but it's a little too late.
