I don't think that envy is a part of this. People hate Trump because he stands in the way of their agenda. This started with the open border agenda, which is really just designed to create more Democrat voters, so they immediately accused him of racism. The moment he talked about criminals and rapists coming across the border, some people legitimately thought that he was racist, but others just saw him as an impediment to their plans. The fact that he reflects the opinions of many Americans, if not the majority, and mostly tells the truth in his own boorish way doesn't help.
