Learned what? When it's zero interest rates, funding from desperate investors would dwarf any possible profits you could make, and the bigger headcount makes raising money easier.

It's the policymakers and society in general that should learn. A decade of low interest rates together with outsourcing of everything that can be outsourced created hordes of useless people that add little value and feel entitled to their salary. As you get more and more of those, the value of money decreases, and inflation starts piling up (COVID accelerated it nicely, but things like housing, educational and medical were off the charts for a long while).

The hangover from those rates will last longer than most expect.
