The central premise of this post is basically not true: working conditions and wages have pretty consistently improved over the past 200 years. The cases where it didn't were generally offset by the rest of society benefiting from increased automation and productivity. Where the current revolution will lead remains unclear, but if the past is any indication things will probably continue to improve for most people.
Two hundred years ago meant widespread child labor, harsh factory conditions, little worker protection, and slavery or serfdom. Add to it the onset of Industrial Revolution.
Modern studies indicate people in the dark ages worked 6 hours a day: Ironically a better baseline!
