I know it's a weak argument. I just don't like Billy Gates with his silly voice and all his $$$, jammy so-and-so
Now that is an emotion that I understand, quite typical, actually. Such it was for Rockefeller, Carnegie, etc. All the industrialists that became very rich building great corporations and succeeding where others couldn't. Basically, just simple class envy of the very rich.
Most people, generally the less intelligent, take it one step further from just general dislike to hatred. You see, they don't know their own limitations, of course, and since they can only earn a pittance honestly, they can't understand how someone with exceptional intelligence can earn millions. Therefore, they can only assume that the fortunes, such as Gates', are ill gotten.
