yes, philosophically and by the vibes, we are in complete agreement. clearly inequality is growing, clearly that is bad.
but you're doing a disservice with completely bogus claims like "incomes for lower and middle-class families have fallen since the 80s". it only makes it harder to talk about the real issues and facts, because why would the other side stick to them now? the trust between sides gets further eroded and the gap widens
there's enough real data that we don't have to start making stuff up. the author could have easily pointed to housing instead like you. i think it's actually extremely important to get these facts right. enough to argue about on an internet forum on a sunday evening
