> a low-res 28” color TV with 5 channels cost a fortune.

Uh, back in 2000 (okay not quite 30 years ago, but getting close) I had a 36" Sony Wega which cost around $1500 with DirectTV and hundreds of channels. A 25" to 27" TV was more of a 1988 kind of thing (which is almost 40 years ago now). Being limited to 5 OTA channels was more of a 1980 thing.

But again you can't really buy that Sony Wega anymore, even though the CPI probably prices it at $20 these days.

Back 50 years ago, average household spend on the Internet was also $0, so it was very cheap, we weirdly didn't spend anything on it when I was growing up. Now I spend $80/month on it, and have trouble finding anything cheaper around here.

If you want to consider "communications spend", back in 1988, you might have spent $50/month on your landline, cable tv and newspaper subscription. Today households tend to spend $280/month on internet, wireless and streaming/cable services. That is actually double the CPI. They get lots more for that, but the cost of being an average middle class household has grown at double the CPI. And these days you need the internet in order to keep up with Joneses, it isn't really a choice.
