~1970 is about when the % of workers in unions really started to fall in the US.
Since then the captains of industry in the West have been able to arbitrage labor world wide. Thus labor unions in developed nations, a symptom of labor scarcity, lost their leverage.

We live in Brooklyn near the water. The entire coastline from Red Hook to Greenpoint was once dedicated to the loading, unloading, and storage of pre-shipping container cargo. This industry employed many thousands of people. It was a dangerous job but it sustained families, and it was a bootstrap to a career in the shipping industry. (There are analogies in textiles and meatpacking, in this same city).
Now, the warehouses have been converted into housing, coffee shops, art centers, and the like. The working class job is the service industry (waiting, serving coffee, delivering food), and it’s a very different culture from the working class job of the 60s.
I’m not at all saying the technological innovation was a bad thing. But it did have a huge impact on the local economies of every seaport in the world (Bay Area included, for those that live there).
If you’re interested in learning more, there’s an 8-part audio documentary on shipping containers. You can listen to episode 7 about automation here: https://soundcloud.app.goo.gl/AfzxGaUKuceh4W9W7
I have a feeling that use of expanded polystyrene foam (colloquially styrofoam, which is actually a brand name for a different material), as a packing material had a great deal to do with the trend as well. Loose foam packing peanuts were patented in 1965, I'm not sure when foam cushioning blocks were introduced.
We've also seen a great domestic expansion in the upper middle class and a reduction in the lower class since then. More people are "middle class" than ever before with a larger percentage being "upper middle class". However, the middle class feels further away from the upper middle class in large part because there are simply many more upper middle class people than ever before (and more upper class for that matter).
I'm not trying to make a counter argument or anything but just trying to make an argument that we can't do an apples-to-apples comparison between today and 1971. Relative wages are less for a group of people, but consumer goods are relatively cheaper as well. Home prices are relatively higher but interest rates are far, far lower. The middle class has grown and poverty has been shrunk to record low levels (people often forget how many people were impoverished in this country not too long ago) but a lot of that growth has been in new upper middle class people.
We've seen union participation fall, yes - but have we asked "why" it has fallen?
Proof: look at stock returns when management pays more wages vs cuts wages/jobs

- read first three graphs... "oh, yes, that looks like a problem"
- scroll next 5 graphs... "oh, looks like lots of evidence correlates to that year... what happened that year?"
- scroll next 5 graphs ... "oh, wasn't it the gold standard that year?"
- scroll to the end.. read quote .. "is this a bitcoin quote? No, someone else... wait, but who is River Financial and why do they want me to care"
So, what about the (perhaps too simple) explanation that 1971 is when the developed world finally caught up from the destruction of WWII and investors recognized this? That would mean an end to free wealth for the US, as factor productivity is no longer the highest in the world.
Effectively what we're talking about are central bank operations, which is a dry and boring subject within economics, that is both misunderstood by mainstream economists and misused (for political reasons) by heterodox economists (many of whom are charlatans).
Generally speaking though, everyone tends to agree that central bank policies became looser over the 20th century, and IMHO that's really the only relevant kernel of truth in the OP link, who seems to be a promoter of fringe economic theories.
The best place to read about the topic is at the Federal Reserve Bank's website. Alternatively, I would recommend reading any of this :
