Again, just baseless conjuncture that sounds "almost right". You have the general principles, you even reference Econ 101, but analysis and expert opinion goes further (why there's so many armchair champions out there, unfortunately). Please cite some actual sources that have analyzed the systems and what your perspective has been formed by. This just seems like base-level pandering that gets no where like a "group chat" on one of the mainstream news outlets.

Things do not happen in a sterile chamber. You can't create union movements when they're getting destroyed by officials

For approximately 150 years, union organizing efforts and strikes have been periodically opposed by police, security forces, National Guard units, special police forces such as the Coal and Iron Police, and/or use of the United States Army. Significant incidents have included the Haymarket Riot and the Ludlow massacre. The Homestead struggle of 1892, the Pullman walkout of 1894, and the Colorado Labor Wars of 1903 are examples of unions destroyed or significantly damaged by the deployment of military force. In all three examples, a strike became the triggering event. (link)

Your AI argument is fear mongering, as I stated above, with sources, a net increase in jobs is projected. This is the telephone/computer technology fear now for the 2020's. You've yet to provide an actual argument for why technology shouldn't proceed. Should oil and gas not go through the same transition? God forbid we have less administration and more skilled workers, as my sources concluded would be the outcome.

Yes, supply-demand is a fundamental pricing mechanism, as econ 101 will teach. Unfortunately the subsequent classes that economists take after also include the million different factors with changes that mechanisms output. For further understandings, I would suggest Unlearning Economics (here is one of his videos going over a Sabine Hossenfelder's video on capitalism). He comes with credentials,

My background is as an economist who specialises in behavioural economics. I did my PhD in economics at the University of Manchester and from 2019-23 was a Fellow at the Psychological and Behavioural Science Department at the London School of Economics. I remain affiliated as a Visiting Fellow.

I have quantitative skills including mathematics, statistics, and coding which are illustrated by my PhD and current research. I am also a published author, with my book The Econocracy selling 15,000+ copies and having over 200 citations on Google Scholar. I also have excellent communication skills and have presented both my research and book at numerous conferences and universities.
