Why does a private school charge tuition unlike public school?

Private schools charge tuition because they are not funded by the government (or at least not primarily). Public schools, on the other hand, receive the majority of their funding from local, state, and federal taxes. This means public schools are largely supported by the community as a whole.

Since private schools don't have this consistent stream of public tax revenue, they must rely on tuition fees and other sources of funding like endowments, donations, and fundraising to cover their operating costs, including teacher salaries, building maintenance, resources, and other administrative expenses.
