Why at lower wages? Most automation has led to people transitioning to higher wages. Utility works get paid 10x more than lamplighters. Why would that change here? Your job will have a bigger impact, affect more people, and you'll be doing more with less.
I am not saying all employers will immediately start paying people more, but economically it doesn't make sense that pay will go down.
The economy now is very different, no gold or silver standard, less isolation and more globalised product chains and processes, and 7-times as many people.
There is a good chance that a large enough number of people will suffer from this transformation, and they will have to fight with whatever they have, because if they don't, they will risk being left on the roadside and not getting any raise.
People having some direction over how jobs are automated should keep that in mind, otherwise it will be too late to convince the masses of people fearing automation that it is their fault not seeing the positive angles of automation.
No, what you mean to say is that automation has eventually (decades later) led to higher purchasing power in the system as a whole. The outlook for people that were directly automated away was pretty bleak, actually. The hundreds of thousands of lamplighters did not largely become the thousands of electricians that were needed in this new industry.
This tracks for all industries. Automation literally means far fewer people will be employed to do the same job (otherwise what's the point of it?). That dumps these workers out at the low end of the general job market, where they have to compete with an increasing number of people. Because of the desperation to get any job, the wages fall. It's only decades later that societies settled into a new place and created enough brand new jobs to make up the shortfall, or applied regulation to reign in the crazy power imbalance. That's the stuff you miss out on if you only look at statistics that span centuries and treat the population as one homogeneous mass. The people who are directly targeted by automation are very likely to have their lives messed up for a very long time.
Gonna need a citation for this.
