The "mills"are IMHO 10 times better than the US "get any hour anywhere"
approach as long as airlines are involved in the training...
You are entitled to your opinion.
But in my opinion, having worked in training, flight standards and a Chief Pilot's office, you are wrong. You find good pilots from all backgrounds, but to make one with an arrogant sense of entitlement, poor motivation and laziness -- that takes a pilot puppy mill.
Someone who has built 1500 hours clearly wants to be in aviation and has probably learned a few things along the way, both about aviation and life. They will have a degree of maturity and won't need a silver spoonectomy.
