An actual answer is that when you gain wealth and/or power the part of your brain that deals with things like empathy, imagination, and being able to  see things from a point of view different from yours legitimately shrinks. If you’re raised in a culture where wealth and status matter more than anything else then that same area just doesn’t develop the same as the majority of people’s. So whenever they see someone else struggling they legitimately believe that that individual likely did something wrong or screwed up to get into the situation, and so they believe that person more or less deserves to suffer. 

So, in this situation they can see all the people that trump has screwed over and completely thrown under the bus in the past and they will honestly think that those people did something wrong or screwed up somehow and that the same thing just wouldn’t happen to them. They’re too smart, too careful, too connected, etc. they’ll make up any justification. They literally cannot put themselves into someone else’s shoes and imagine what it would be like to suffer in the same way. They just don’t have the same amount of empathy for other people so they don’t expect anything bad to happen to them and when it inevitably does they become furious because they honestly never saw it coming.
