I have watched this guy occasionally.
He's a socialist. I don't agree with everything he says but usually presents things well.
Basically he says that as capitalism fails elites will tolerate fascist tendencies eventually leading to outright fascism.
My philosophy is slightly different. If economic conditions detiorate people will drift to extremism in general. Ideally don't let things go that far.
Alternatively people will pick fascism if the alternative is worse eg Baltic States over Stalin's regime.
Of course the worlds not ideal and this neo liberal trickle down is BS.
