I love these deranged financial rules of thumb developed in a tiny slice of time in america that everyone is supposed to live by.
30% to housing, 10% to cars
These were made in the 70s and 80s I guess? Not only is today so different that these guidelines are fucking stupid, but even in the 70s the world was still recovering from post war boom. Prior to WW2 the economy was completely different! People didn't save, there were widespread recessions, from nance didn't have the stranglehold that it did moving into the 70s and 80s too.
I bet someone looked at their finances in like August 1976 and made up rules that persist to this day and are absolute fantasy
