Also, absolutely no unions in the public sector.
Why?
Public sector unions create perverse incentives. Their members are paid with public funds allocated by elected representatives. Those salaries are then used to pay dues to the union, which then uses that public money to lobby public officials to increase the salaries. Then the salaries increase, and so does the union's take. This is a vicious cycle that is too dangerous to be allowed in a free society, and the police and teachers' unions in this country are hard evidence of the havoc this system can wreak.
Some kind of perverse incentive exists. But it's way worse if they don't exist. Teachers and others provide vital services to society and if they aren't unionized, then they can suffer immense burnout and unhealthy de-prioritization thanks to the decisions of the elected officials.
Teachers and other public employees having unions is as important as the public sector itself is. Which means, quite significant.
Sometimes I wonder whether the majority of Americans even see Public workers as human. Im serious, the way you hear right wingers talk about teachers, its like they see them as automatons rather than living human beings.
