Technology has been decimating jobs since the industrial revolution. But all the jobs destroyed were in India and China. They had 25% of the world GDP before industrialization. They had even higher fraction before the age of exploration distributed cash crops (sugarcane, tea, coffee, breadfruit, cotton) around the world. So for centuries all the philosophers, economists and sociologists did not even understand the full impact of the industrialization. Mostly they saw it as political issues, colonialism, anti-colonialism, etc etc.
Read the The Rational Optimist by Matt Ridley to get an idea of the doom and gloom being predicted for centuries. Matt takes the view all these gloom predictors were wrong and the industrialization is an unadulterated success for humanity. He seems to think humanity consists of Europe and USA.
This review sums it up nicely
The job destruction is also accompanied with wealth transfers and power transfers. Finally the job destruction finally lapped up the shores of Europe and USA by 1980s. Slowly middle class of America is waking up to what has been done to them. Their jobs are gone. The "wealth" they have as home equity is a fickle fictional paper gain. Their pensions are gone. Their investments in 401K funds is being used to transfer more power to the top 0.5% of the rich.
Typically very smart and hard working people end up in the top 2% by income and usually end up in the band 98th percentile and 99.5percentile. (To reach the top 0.5% you must have inherited wealth or take huge risks and be lucky). The wealth transfers from third world to industrialized nations had run its course, wealth transfer from the bottom 80% to top 20% has run its course. Till then these guys were very happy and egging it along. Now there is no real wealth left below 90%. The momentum of the economic policies set in motion by them is taking money from the 90 to 98 band and moving it to the top 0.5%.
If you finish college and get in to the 99% cut off entry level salary and stay exactly at the 99% cut off all through your career, it is not enough to get you into the top 1% by wealth (5 million according to IRS and 8 million according to the feds). Till about 2000s, top doctors, lawyers, accountants routinely made it to the top 1% without inheritance. Not any longer. Citation provided
