>realize that some members of the middle class have more in common with billionaires
Well they benefit from the system and will never turn against it, so yeah from the POV of the potentially revolutionary proletariat they are allies, but that doesn't mean they have all that much in common materially.
A lot of western so-called-leftists are exactly this group of affluent city dwelling group of people who are really liberals at heart. That's the mainstream "left". I think the actual proletariat haven't yet found a way to organize, this is still in its infancy.
