What's changed, and I know this from running a business for over 30 years, is the mindset of the generation(s) that came up behind us. I had countless interviews with college graduates that came in thinking they were management level qualified right out of school. They expected salary, perks, and recognition for having that "onion skin" in their hand......
Same with officiating. The younger generations have the mindset that they should have coming in, what most (remember, there's politics involved) have already earned.
