She is so right about the planned obsolescence. I first started paying attention to it about 8 years ago... things are not being made like they were in the past, and the first culprit I noticed was major appliances. What our parents bought that lasted for 20 or 25 years now has a lifespan of 8 or 10. But did the cost go down? No way!
Clothing the same on a smaller scale. And even smaller still, I noticed a few years ago when tuna cans went from 6 oz. to 5 oz. Did they think we wouldn't notice? But they didn't have to raise the price too much... just give less food and maybe no one will catch it. Shrinkflation is showing up more and more every time I shop.
