Re: Stupidity plus arrogance
I find that in some social contracts the insecure ones are the arseholes, because they're worried people think of them as jumped up little people - and we do, but only because that's how they act.
In general, decent human beings tend to be decent regardless of wealth, and arseholes are arseholes whatever their bank balance. On the whole, though, decent human beings tend to get on ok in life and are more likely to be reasonably well off. Apart from a handful of scammers and crooks, everyone I've ever met with money has been nice to deal with , and that's clearly helped them make it to the level they had.
