You don't even have to be that old to remember most of that. Except for milk deliveries, well-dressed for airplane trips, and a few other things on there I remember how things were...

If you think about it, it's all before super cheap labor/parts from China, not just a technological gap.

One of my more earlier memories is standing in line for Star Wars. It went clear around a building or two and as a child it was the most spectacular thing to see that many people in a row.

Oh and I remember being given a nickel to buy a bagel. Damn I've gotten old :-(
