Not sure if it counts as privatized when the vast majority of Americans are homeowners.
The gov had a ton of programs to increase the home ownership rate over the last 50 years, they were somewhat successful. Now you have a situation where the networth of 65-70% of the population is tightly coupled to their home price.
And we wonder why it's so hard to get them to vote for new housing.
As Munger says, Show me the incentives and I'll show you the outcome.
