Here’s two ideas that liberals/progressives/Democrats tend to agree upon: 1) predatory pricing is an effective business strategy that’s used often enough to be worth regulating, and 2) K-12 public schools do a good job (and in Mayor de Blasio’s worldview, good enough to justify ham-handed efforts to eliminate the competition).
Byran Caplan makes an astute point about this: K-12 public schools in America have been practicing predatory pricing for decades.
And look at what it’s got them? They haven’t driven their competitors out of business. And, when the competitors are relatively unhobbled by regulatory changes, they thrive.
This should be used as a counterexample any time someone brings up the idea that predatory pricing is an effective management strategy.
