This is indeed the irony behind so much of this.
Here's a trend: people who are wealthy, but got wealthy by doing "real stuff" - things that create actual value, resources, and material improvements for society, show an interesting trend of not being arrogant greedy assholes who believe they're Anointed Ones. They tend to be the wealthy people who give much of their money to charity, invest in real public works, etc.
By contrast, people who become rich by gaming the system, making money by moving money around, tend to be those who lock their wealth in a vault and sit on it. They tend to be the arrogant pricks who think that they're simply more clever than the average person, because they figured out how to come out on top and join the class that dominates society. These people often give the impression that they're actually quite stupid in a general sense (outside of being skilled at the specific avenue they took to power and wealth). And they also tend to be the sociopaths whose inability to feel like a human being aided them in screwing their way to top.
People who become rich by doing real work at least understand that work is hard - all work, from doing dishes to designing silicon wafers. Anyone who works deserves respect, and already has a "real job". They also tend to comprehend that much of their success is built on luck - they may have worked hard, but the difference between themselves and someone who "failed" is often the capriciousness of fate. They were in the right place and time to jump into an opportunity, while another guy who worked just as hard got screwed.
Rich assholes have no understanding of any of that. They simply enjoy the feeling of franchise and superiority their position gives them (as the world of the rich is designed to take advantage of their money, and sell them a luxurious, exclusive life experience).
