You're absolutely right. The life of a worker in early industrial Britain was pretty crap. Much like the situation now in sweatshops in China etc - but it didn't last. They got together and won better working conditions, pay, health and safety, the 8 hour day etc. This was replicated in other industrial nations.
Now, none of us would really chose to go back to pre-industrial times. You only have to look at the difference in life expectancy between developed and developing nations for one example of why having a modern industrial society is better. And certainly it is also reflected in the huge historical mass migrations to the west in search of what is perceived to a better life (although I agree, I do wonder sometimes about that suppose better life?

).
