More often than not, it's the other way around. Being born in the bourgeoisie, like Trump and Musk, grooms you into a certain way of thinking. You're told your whole life you are exceptional, above everyone else. No wonder they turn out like that. Read up on both of these guys' educations if you're interested in this.
Both Trump and Musk may have been born into “bourgeoisie“, but the connecting and relevant factor here is a highly traumatizing childhood with highly traumatized parents.
With the kind of analysis you give we're stuck with surface level "oh they're just a bad batch", when they're pure products of a system that makes series of them. It's not like they are thousands just like Trump, ready to step in if he loses power.
The bourgeoisie has a material interest in installing fascism, which is why we're here. Bezos, Musk and Zuckerberg are among the only ones to profit from the current circus.
It's not the first time it happens either, this has been proven times and times again. Look up the relations of Hitler and Mussolini with the capitalist class of their times.
