While I believe your idea is with good intent and I am not going to bash you, I would strongly consider going back to the drawing board on this idea. I can't even imagine the number of ways this could possibly go wrong. From punishing lower-income students where parents are able to compete for the "good teachers", abuse by parents to punish a teacher, and even going as far as to create a racial barrier within the school preventing access to "good" teachers by parents blocking access to classes.

The number of ways this could possibly go wrong - It's true. It could end up being a disaster. But there are also probably unimaginable ways it could go right.

Lower-income students being punished - Lower-income students are already being punished for living in poor neighborhoods and being forced to go to terrible schools. Parents are already competing for good teachers by moving to wealthier neighborhoods. It wouldn't bother me one bit that some kids would get better teachers than others because I believe this system would provide better education for all students in an absolute sense.

Abuse by parents - I'm not sure what mean by "abuse". I am certainly not advocating for physical violence. I wouldn't use the word "abuse" for teachers having to be responsive to parents' demands.

Racial barrier - I'm not sure why anything in this proposed system would inherently be racist.

To address "abuse by parents", I am not referring to physical violence. Abuse by parents in the sense that a group of parents can conspire to "punish" a teacher they perceive as being unfair to their child by not bidding on that teacher's class, potentially resulting in the teacher being fired.

The racial barrier doesn't mean that it has to be inherently racist. It can simply mean that, for example, white parents avoiding African-American teachers. Or vice-versa. A bidding system such as this could potentially result in an unintended segregation within the school.

In many school systems, there is already a "bidding" process among schools that put the good teachers at the good schools and the bad teachers at the bad schools. It is called school choice and allows parents to choose which school their child goes to.
