“College, cars, homes, most things were cheap for Baby Boomers.”
The list price on my mother’s 1968 Pontiac Firebird was about $3500.
That would be about $40,000 adjusted for inflation.
In 1979, my college tuition was $4,000/year, or about $28,000 adjusted for inflation. Middle class whites pay more nowadays to help subsidize the “underprivileged”.
It looks like you’re right about cars and wrong on college.
