VK points out, quite correctly, that survivorship bias doesn’t completely explain our perception that things are getting worse. He is right. There are many other reasons; some have to do with perception and some with reality.
Actually, in the first place, I don’t just find the idea that home appliances have gotten worse incorrect – I find it incredible. From my point of view, it is so obvious that things have been better in the past 15 years than they were in the 15 years before that, that I question the honesty of those who claim otherwise.
