The Sam Vimes “Boots” theory of socioeconomic unfairness, often called simply the boots theory, is an economic theory that people in poverty have to buy cheap and subpar products that need to be replaced repeatedly, proving more expensive in the long run than more expensive items.
Sunglasses. Would go thru 4 or 5 pairs of cheap plastic lense sunglasses every year. The lenses would always get all scratched. Bit the bullet and bought a pair of Costas 3 years ago. Lenses still look brand new.
I’m the opposite, I bought a couple of £3 pairs with the view of not caring if I lost or damaged them, still going strong years later!
Yeah, ever since polarized plastic became cheaper than coloured plastic, you basically can’t go wrong anymore.
