I'm trying remember a case of where a public utility / service becoming privatized resulted in better outcomes for the public in the medium or long term.
The two best examples I can think of are the DMV in Alberta, Canada, and alcohol sales in the same province.
Prior to prioritization, the DMV was run by the govt and it sucked, hard. Two locations in a city of 1M. Took forever to get stuff done and the hours sucked (like the DMV in the US!). Post privatization, it was awesome. About 50 locations in the city, open until 9pm at night so you could go after work, good customer service and no lines! The difference was night and day.
Alcohol sales were similar. Better hours, better prices and more convenient. Specialty stores opened up and actually catered to customers needs versus the old govt run stores.
They don't all need to be socialized of course, but the raw foundation of society (health, education, police, fire, even rail, etc) put people on an even footing that allows them to rise to the level of their capabilities. It provides a foundation for meritocracy instead of supporting plutocracy.
