Industrial revolution cities were famously a meat grinder though. Disease, poor quality accomodation, reckless safety considerations in early factories meant a lot of those displaced from rural artisan jobs to work in the cities literally died as a result.
Many of the new jobs' employees were from population growth, people that lived in the countryside thanks to the growth in food production that otherwise wouldn't have, then moved to the cities, etc, as sanitation improved a general fall in the death rate prior to the fall in the birth rate (but later than the initial migration to cities).
Nor was the city standard of living equivalent as people move from rural households (admittedly often multi generational ones, so more crowded than modern ones) to overcrowded tenements.
So the story people gloss over is that all the rural cobblers went to the city and became factory workers and everything is fine. But while it might be a reassuring story that _society_ survives and evolves, it's not at all clear that individuals did as well.
