They support the rich like John Kerry, the Kennedy clan, the Hollywood crowd, and the sports stars, because these types of people represent a kind of rich that isn't generally accessible to most of society. The left, social elites, and many democrat voters resent those who did well because they worked hard and did what others could do, but didn't.
For separate but congruent reasons the left supports a societal structure that consists of an aristocracy and the homogeneous dependent masses.
A lot of these lefitsts think that life is just about luck, not about a process that leads from one thing to another and so forth. The bricklayer, as you mentioned, starts small and through study and a series of good choices (plus admittedly some luck), ends up with this own business and makes a tidy profit. Success is a process, not just taht one lucky break. It isn’t, it is learning the right skills, thinking things through, and also being self dsiciplined and not carrying a chip on your shoulder against the rest of society. I am so sick of how so many of these idiots don’t mind making gobs of cash, but would prefer it that they ‘stay in their place’ and not make their own living.
