The "he lived in Daly City" thing is a bit of a red herring. Daly City was not a 15 minute drive from the center of the hottest industry in the world in 1963. So substitute Fresno.
Anyway, if you can find a woman who wants to be a SAHM to your five children in a Fresno starter home, where she clips coupons and cooks meals from scratch with no appliances, you can achieve a 1963 standard of living pretty easily on a schoolteacher's salary.
Not every house at that time was a post war levitown style shack. AC wasn’t even terribly uncommon in 1960s construction.
Most of the "life is too expensive today" complaints are some flavor of: Grandpa was a 90th percentile income earner and I am a 50th percentile income earner, so even though my life is objectively much better than Grandpa's in many ways (childhood vaccination, clean air, seatbelts, etc) the loss of status is much more salient than the gains in material well-being.
Air conditioning was extremely uncommon in my neighborhood when I was growing up in the 80s. I didn't personally know a single family that had a/c until the 90s. The only places that were air conditioned in my neighborhood in the 80s were businesses. I'm sure it was more common in the South.

That song is about Daly City,[1] where some of the original houses still are pink, green, blue, and yellow.
If you mean "where within commuting distance of the hottest industry in the world can I find a reasonably priced home" then yeah obviously you can't, but SF wasn't that in 1963.
This is a key point. I grew up in a nice middle class neighborhood 20 minutes from DC. Back then DC was the murder capital of the country, there were no tech jobs in northern VA, etc. Today it’s much more expensive, but it’s also full of tech engineers. The town has moved upmarket. It’s not a Honda Accord, it’s an Acura.
This makes "thriving" a constantly moving target, because by definition 40 percent of people have housing that sucks too much. This does reflect realities of human psychology (our happiness is mostly about relative well-being, not absolute well-being), but it is not remotely useful for comparing material living standards over time.
