Wars of I BC century and Roman laws that put people into slavery for debts had brought hundreds of thousands of slaves into economy bringing cost of labour close to zero. Conquest of Egypt and North Africa flooded markets with cheap grain.
That market disruption made artisan shops and small farms unable to sustain/compete on the market with larger enterprises based on slave labour.
Majority of citizens of lower class had been then entitled to free food and free entertainment (bread and circus). It was necessary for keeping their votes and for keeping appearances of the republic. (Even what we call Roman Empire were still nominally a Republic with Senate and elections held for various offices every year at Fields of Mars).
I recommend everyone reading Rubicon by Tom Holland. https://www.amazon.com/Rubicon-Tom-Holland/dp/1400078970
I voted for Bernie personally -- not a full out socialist... but I do think single payer + ubi + free college makes sense -- take the stress out of living paycheck to paycheck... at least somewhat... Not saying make everyone a millionaire and inflate the crap out of thnigs...but there needs to be some equilibrium...
One good policy might be capped CEO pay at say 200 * average employee salary. In this way - for CEO to get a raise, average salary must go up -- this can happen either by raising across the board or by moving more people to management and increasing upward mobility. Any money the CEO makes over 200* from that company is taxed at 100% including benefits, stocks, etc...
I'm currently very impressed by the work of Prof. Richard Wolff, an economist that heavily criticizes Capitalism and tries to make actual practical changes in the lives of people starting from their workplaces.
Here is a talk he made in front of Google employees (the irony): https://youtu.be/ynbgMKclWWc
I do like UBI though along with (the pragmatist in me) believes gov't should work like agile dev teams... push changes up to a github like interface for bills.. the all bills should be VERY succinct and serve 1 goal, and that they should be repealable pretty easily like reverting a change on github... I think we have WAY too much bloat, and omnibuses just don't make sense at all and should be illegal.
Congressmen make very good money and benefits -- and have lots of perks so they should be required to work as hard as the next guy in America - -40 hours per week IN congress discussing bills and voting - -anything to 'market' themselves for future elections is NOT part of their job and outside their 'paid' duties and should be done on their own time.
I think automation, etc will disrupt the entire fabric of society soon, and honestly I hope we can move back to middle-age work days... they worked maybe 20 hours a week, if that and some weeks not at all - if farming the winter was pretty much just don't freeze to death... While their lives weren't long, I have to think they enjoyed life more than we do today.
If I could live for free (no rent, free food, free electricity, etc), I probably would quit. I don't have much savings and my quality of life would drop a little, but I would probably take 6-12 months vacation and just dick about, playing video games and concentrating on my hobbies.
