How to fix the school budget and social problems

One way I imagine of easing the burden on the public school system is to apply a concept that privet schools have. No we don't privatize them. We rent out class rooms after normal school hours are finished. We rent them out to people who want to teach classes at that school. Now hold on, just hear my idea out.

Lets say we rent a class room for 400 bucks. A person within the community could pay rent to use that room (not tax money) and teach a class. That person who chooses to teach the class, could charge a rate for attendants. So if 40 people are expected to show up, you could charge 10 bucks to cover the fee or more if the teacher wants to make a profit.

Now as for the subjects being taught, it would be up to the teacher. They would design the curriculum and the testing method. None of witch are dictated by state or federal government. People with or without a teaching degree could come in and set up class about the subject they want to teach. So long as it is within reason. Meaning anything that might derogatory would ban the person from the school. Now these classes could be unorthodox, simply because you would not find them in a normal public school. You could see classes that teach creationism, tie-chi, religion, politics from a point of view, or anything in between. Companies can even hire people to teach within the public school to fill a gap within their company. Maybe a union hall set up an agreement with a teacher, that if they teach a trade to the students, the students would be eligible for a job with the union hall and get good money.

No tax money would be used, and a set rate would be charged to pay for usage of the facility. The teacher would provide their own materials and teach the students their school of thought. This could bring in a decent profit to any school. Not a lot, but could lesson the burden by creating their own funds. The money would be added to their coffers and they can use it as needed, but will be treated as tax money. The only problem you would have is, what would constitute as a school sponsored club or a privet study class? Simply, if the school chooses to sponsor the club at the discretion of the principle as is now. The details would be worked out between the school and the teacher. The best part about this is that the community is finally involved more now than ever in the schools education. The school doesn't use tax money or award degrees upon completion of a privet study. The best part is that it even gets a new source of income to help keep itself a float.
