> My take is that we need to tread a thin line such that we teach young people to accept that life is inherently unfair, while at the same time doing what we can as a society to make it more fair.

Agreed. Teaching that life is unfair (and how to succeed despite that) is an important lesson. But there's an object-meta distinction that's important to make there. Don't teach people that life is unfair by being unfair to them in their education and making them figure it out themselves. Teach a class on the topic and what they're likely to encounter in society, a couple times over the course of their education.
