"liquid crap" is obviously exageration but if you take a truly random slice of population 90% will be any combination of not interesting/not a nice person/hidden agenda or want to exploit you/have crazy views/...
many of them are higher class than me. in absolute numbers it's more lower class simply because there are fewer rich people than poor people but take 5 truly random people of either high or low, I think you would agree with me that only 1 at best you would want something to do with.
