Things that should never have been privatized (& for profit)
1. Education
2. Prisons
3. Health care and mental healthcare
4. Essential utilities, especially water and electricity
5. Retirement
6. Emergency services (fire and rescue)
7. Safety (especially allowing companies to 'self regulate')
8. Military

Just remember, 99 times out of 100, once a company goes 'public', shareholders' profits become more important than ANYTHING.

@Darkphoenix These weren't actively privatized. They started out as private, voluntary endeavors, largely via donations to churches (always been a pipeline to power). Think monks hand lettering *all* the books, and about half of western hospital names starting with "Saint."

The ethical issue upstairs is whether people should be compelled by government power (guns, prison, fines) to provide all of that... which is effectively the flip of communism.

Not arguing for/against. History matters.

@janisf many prisons were actively privatized, and it costs the government more, per person, per day, than what they were paying when they were run by the feds. Oversight was minimal, abuses were/are rampant. With the added incentive to sell the labor of inmates for a huge profit, they routinely block parole of non violent offenders in order to retain their docile work force. The inmate is lucky to see 1/10 of 1% of that money. In addition, they are paid by the head, so they like to run at 50% over capacity, using recreation facilities as dorms.

@Darkphoenix OK, true, (in 2022, 8%*) thanks in large part to public policies of the 80's & arguably moreso 90's. It might aslo be argued that state-run prisons aren't any better. Possibly easier to oversee, but not necessarily better.

That's not what you're arguing, though, and not what I was addressing either. We have a tangled private public mess in part because so many of us haven't dissected its roots.
