Economics are hated because economical arguments are used to justify why we cannot do the necessary things all while doing things that bail out the rich for the tenth time.

You don't need to be an economist to realize who is getting fucked over. I am not from the US, but a vote for Trump for many was just a vote to burn it all down, especially because the other candidate was perceived to standing for perpetuating the status-quo.

I am not saying I like Trump. In 2016 when he was running for the first time I stood behind the back then very unpopular opinion that he is a fascist and I would have loved to have been wrong about it.

Economists claim to be like physicists, neutral and just observing, but somehow the economically benefitial measures always benefit the few at the cost of the many. Now that has nothing to do with economics per se. Marx was an economist after all. It has to do with how economics are used by the political class.
