I'm curious if the inflation-adjusted prices of those long-lasting early microwaves were less than the cost of 3 current microwaves that last 7 years. Also, this isn't an apples to apples comparison because they gradually lost performance over time and it took longer to heat up food as they aged.

This is a common myth that was debunked a while back. Essentially people get fooled by survivorship bias: they only see the few old appliances that somehow survived, and that leads them to conclude that things were higher quality back in the day.
