edit: didn't realize I was feeding a troll. Feel free to ignore.
I expect the objections are in how quality is measured and enforced.
It reminds me of education system in the US - most people (project 2025 aside) think it's good to have a public education system; having a pipeline of skilled workers makes it easier to build an economy filled with a diverse set of businesses.
However, the attacks start to fly when there is disagreement about who should be allowed to teach, how they should be measured, and how they should be paid.
