Higher social classes have always despised the lower ones. Imagine going to ancient Rome and saying that slaves should be given full citizenship and treated as equals.
"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.
