And yet I would contend that suburban migration in the post-WW2 period was only possible because the U.S. government had implemented two of the biggest pieces of socialist legislation in our country's history: the G.I. Bill and the Interstate Highway Act.
It's also worth noting that the post-WW2 period was an anomaly in that the U.S. was the only major industrial power in the world to emerge from the war with its industrial assets and infrastructure unscathed. As the rest of the world caught up to us over the next 20+ years, the U.S. lost a lot of its competitive edge in the industries that played such a big role in this suburban migration.
People keep repeating that as if it were some kind of universal explanation.
The fact is that by WWI the US was already the world's largest industrial power and in the 1920s American workers were already enjoying the fruits of mass production and high wages, something interrupted by the Great Depression and WWII. The comparative US position externally improved after WWII, and that comparative position declined over time. But by the late sixties American workers had reached an unparalleled standard of living.
The combination of going off the gold standard (which opened the flood gates to unlimited unfair imports) and regulatory and tax strangulation via the EPA and other agencies annihilated American heavy industry. For example, American steel was pilloried as old fashioned even as the billions needed for capital improvement were instead spent on meeting EPA requirements, burdens foreign competitors didn't need to meet. Shipbuilding collapsed as most seaborne trade converted to imports using foreign-built ships and container cargo. American car companies were pilloried for not building smaller, fuel efficient compact cars when the high gas prices due to stupid government policies (the oil embargoes are what you get switching from paying exporters in gold to paying in fiat dollars) are what created the market conditions for such vehicles. And then in the nineties we opened up the US market to the utterly rapacious mercantilism of China, losing even more industry.
The fiat money importers and financial speculators got the gold mine. Everyone else got the shaft.
