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.
