Trump is a product of the system. He is corporate America. He may not have come from the political system but he represents what the political system tries to uphold. I get that people were tired of the Democrats and wanted change but it's a bit like us fans cheering on Stan Kroenke to fire Wenger and having a go at managing the club himself because he represents something different.
It was obvious Trump didn't have the intelligence or strength to resist. Resist isn't even the right word. His whole 'You're Fired', no nonsense approach doesn't exactly personify a man that has a lot of empathy for regular working people. His core was always going to be for serving corporate America even if unethical.
