I lived through the 60s and know what the goods were.
TVs, for example. They had tubes then, and crummy B+W pictures. They were constantly going on the fritz, to the point that drugstores had tube testing stations. You'd bring in the tubes from the TV and test them in this device that looked like an arcade game, and buy replacements.
Cars then required a lot more maintenance then. And I mean a lot. I've owned and repaired them.
I can go on, but the point is made.
I'm sorry but I will need a second opinion. I just don't believe there was not a single brand of TV that was reliably good the way some brands of clothes, furniture, power tools, phones, spices, perfume, refrigerators, light fixtures, record players, guitars, lawn mowers, and basically all non-perishable goods on the market were.
You could get the cheap stuff, or you could get the quality stuff, and you knew which is which. Neither of these is true nowadays.
