the problem is that having a healthy community of scholars doing good historical research using sophisticated methods, produces a lot of positive externalities. most people never engage with it but having such people around does limit historical bullshit. this has been good for society. but it's now falling apart.
I agree it’s a positive, but each one of us has to sell our value-add to the rest of society. This is actually a wonderful constraint to have because it keeps each of us in touch with the rest of humanity
Is it really falling apart? The US universities hire many, probably thousans or even tens of thosands, of excellent history professors. What's the problem with it?
