Again, the Sam Vimes 'Boots' Theory of Socio-Economic Unfairness still holds but planned obsolescence where shit, even good shit, falls apart more readily than before.
Sure there could be survivor bias as you state but I still own a crap ton of stuff inherited from the 50/60/70's that's holding up much better than today's cheap plastic junk and items that are literally designed to fall apart, including your dewalts, deltas, milwalkees, mikatas. Not saying that planned obsolescence wasn't a thing back then, it certainly was but it's a fuck ton more prevalent now than it was back then and repairing, something that today's companies are actively fighting consumers against makes it even worse in today's throwaway culture.
That and I still think that the OP of this conversation thread is a bit of pretentious dick.
