Nothing surprises me anymore 🤦‍♀️

I used to be a middle school teacher. Let me tell you this, no matter what I tried, most of my students were failing my class. My class wasn't even hard, they had to do ONE homework assignment per week (usually just watch a small 5-10 minute UKposts video about whatever topic we were discussing and then answer 5 questions about it), they had to do one to two quizzes per week about the lesson (WHICH I WOULD GIVE THEM THE ANSWERS TO THROUGHOUT THE WEEK), and the eventual class project (WHICH I GAVE THEM TIME TO COMPLETE DURING CLASS). The result? Most students would waste their entire class time and not do the projects, most students would not bother to read the notes so that they could Ace the 5 question quiz, and most students would not watch the damn 5-10 minute video (PER WEEK) unless I gave them time to do it in class... I quit teaching, this generation is just too lazy and entitled. The parents are also terrible. Whenever a student has problems, most parents side with the child(ren) and it becomes the teacher's "fault" that their child is failing. Administration does the same thing, "Oh, too many students are failing your class? Give them more opportunities! If they want to hand in an assignment a month after it was due, then grade it anyway! Too many failed your quiz because no one cared to read the notes? Curve their grades!" No accountability, no consequences. Most people (adults and children alike) are lazy by nature, schools are competing with social media, smartphones, laptops, games, and the ever-increasing lower attention span of children. Yet, blame the teachers if the students are not learning.

How is paying on performance inconsistent with operation of a free market?

The producers site a specific example in USA: how it worked and why it quit working.

Look at 2 parent household student test scores. USA outperforms everyone.
