Half of all the people in the world are below average. I know, it's crazy right? Confirmation bias makes us expect others to be like ourselves, but they are not, and you're going to have a bad time when you expect them to be like yourself. This is probably going to sound harsh, but it's true: Children and teenagers innately sneer at others that are not like themselves (so much bullying in schools). Part of maturing as a person is to learn that other people are different and have different needs. Many people don't learn this, and they seem immature as a result, and they are ineffective at dealing with other people.
It does if you consider the part going to your county:
“In 2022, the federal government spent … This is 13.6% of the total spent on elementary and secondary education in 2022. The remaining funding comes from state and local governments, which contribute 43.7% and 42.7%, respectively.”
You've misread that. It is not saying that 43.7% of the state budget goes to elementary and secondary education. It is saying that 43.7% of the funding for education comes from the state. Those are completely different.
