Seems like everything good would have been invented by people anyway, and lots of the bad things are done in the name of profits. Maybe they would have also happened in another system, but the point stands.
What, like, Double Stuffed Oreo's? Can we even call those good?
Well at first it was pretty bad for the newly minted proletariat. Being a factory worker or some other industrial worker was seen as being worse than being a peasant. Certainly the conditions were very very poor. Like, comically so. The poor in London used to have a pint of gin for dinner and pay 5 cents (or whatever brit currency I forget) to pass out folder over a stretch of rope (not hyperbole)
The power of the proletariat comes from their shared struggle and proximity to one another. Peasants had agreements with their lords and I would say that the current labor aristocracy/trade unions that formed from the early proles are equivalent to the peasant class of olde.
Right now the class that has the most revolutionary potential is the precariat/vagrant prole. People who have 20 jobs on their resume by the time they're 30. People who work gig economy jobs or service industry jobs, even homeless and lumpen workers. Trade unions are a useful starting point, but they have too much to lose to commit to revolutionary activity.
