Yes, it was easier for just anyone to buy a car. Now do the rest of the stuff in that post. None of it was accessible to someone who wasn't a upper-middle class cishet white dude in the late 60s.
Cars were somewhat cheaper back then, but they were also a lot shittier. Most odometers only had 5 digits because getting it to 100,000 miles was unusual.
Advances in body materials made it so that they no longer disintegrated into rust by the 1980's, and advances in machine tolerances and factory procedures made it so that cars were routinely hitting 100,000 miles or more by the 1990's.
A 1969 Plymouth Roadrunner MSRPed for $2,945, in an era when minimum wage was $1.60/hour. That's 1840 hours worked at minimum wage (46 weeks of full time work), for a car that could probably drive about 100,000 miles, and required a lot more active maintenance.
Now that cars last longer, too, the used car market exists in a way that the 1960s didn't have. That makes it possible to buy a used car more easily, and for the new cars being purchased to retain a bit more value when they're sold a few years later.
And that's to say nothing of fuel economy, where a Roadrunner was getting something like 11 miles per gallon, or safety, back when even medium speed crashes were deadly.
The basic effect, in the end, is that the typical household in 2025 is spending a lower percentage of their budget on transportation, compared to the typical household in 1970.
The golden age for being able to buy and use cheap cars was probably around 2015-2020, before the used car market went nuts.
Federal minimum wage in 1965 was $1.25/h, which is $12.69/h today. Looks like Alaska had the highest state minimum at $2.10, $21.32 today. Or were you taking more average rather than minimum wage?
Page 45 of this PDF has a good chart. It shows that about 26.8 million men were draft eligible in that generation, and about 8.7 million enlisted, 2.2 million were drafted, and 16.0 million never served, including about 570,000 apparent draft dodgers.
About 2.1 million actually went to Vietnam, and about 1.55 million were in combat roles in Vietnam. 51,000 were killed.
So roughly:
41% of that generation of men were in the military
My first house in 1999 was an older 4 bdrm on 14 acres of land for $50 grand. There were a lot of homes in the 30-40 grand range but lesser yards.
Now those same houses when they go up for sale are selling for 200-250k easily. (My place would be worth more than that.. "hobby farms" like what I are selling for even 300-500k here now.)
About 40% of that generation was in the military. 8% were drafted, but a lot of the 32% who voluntarily joined did so in order to exercise some control over where they ended up. Even those who didn't serve, often had to deal with the overall risk hanging over their head, or were actively committing crimes to avoid the draft. The draft might have only directly affected 8%, but the threat of the draft, and people's decisions around that issue, was a huge part of that generation's lived experience.
I would not have wanted to take my chances of being one of the 1/12. They not have had to worry once it was all over, but while it was happening a lot of people were at risk of being sent to die in a foreign land.
