To add to your criticism of point 3: Dr. Rahman highlights this in his Marxism lecture series. The absolute position of a proletarian may improve over time (I think like... 50% of the world has smartphones)? But our relative position will continue to diminish (the richest people right now are basically running countries within their business and controlling countries outside of it). Even if white proletarian get imperial core treats this fundamental contradiction as a result of the falling rate of profit will remain.
