We did have a computer but it was really a one time expense. At the time computers were improving quickly so I scavenged parts which wealthy areas that threw last Gen hardware away but were better than what we had (and I was a kid with a lot of time on my hands.) Giving a computer to a kid for Christmas in '83 is a very different value proposition than even a family vacation because a vacation is something the whole family does.
My family was working class not even lower middle class.
And even we flew a few times in the late 80s early 90s, and we had a (probably used) Tandy computer that hooked up to the living room TV.
People have different priorities. We certainly couldn’t have afforded a current generation top of the line computer, and we couldn’t have flown every year. But an older computer and the occasional flight were firmly attainable to anyone with stable job if they really wanted them.
Yes, obviously a Tandy or C64 in 1990 is different, but anyway this thread is beating a dead horse. I regret even starting it. It's the kind of off-topic nonsense that HN is filled with these days.
I'm not saying that middle class families flew all the time in the 80s, but they absolutely could afford to if they wanted to make it a priority
A cursory google search seems to bear this out. Cheap flights in north america started in 1978 with some air travel deregulation.
