Lower public school enrollment often means less public school funding.

Fewer middle-class students now attend private schools

Stanford professor Sean Reardon says there are two primary reasons behind this trend. The first is that many parochial schools, which tend to offer more affordable tuition, have closed. The second is that tuition for the remaining private schools has outpaced middle-class salaries.

Private schools are free to experiment with teaching styles

Because they’re not beholden to national curricula, private school teachers can use different pedagogical approaches, like Harkness, which was developed at New Hampshire’s Phillips Exeter Academy. The method brings students to a large round oval table and encourages them to lead the lesson through inquiry.

US school distrists have greatly consolidated since 1940

Consolidation significantly decreased the number of independent school districts from approximately 117,000 in 1940 to just over 13,000 today, mainly driven by efforts to boost efficiency and balance funding across communities.

For-profit schools are not beholden to educational missions

In 1996, more than 7,300 companies traded publicly on US stock markets, but that number has recently dropped to 4,300.

Second, the IPO process is expensive and time-consuming.

While 64% of eligible voters cast ballots in the 2024 presidential election, turnout in municipal elections is usually below 15%. For school board elections—where members oversee more than 50 million students and $600B in spending—turnout is often around 5%-10%.
