It is capitalism, not economistism or whatever. Capital decides fate of the economy, not economists or government. Economists only advise government what to do, their advices are only advices and in this status quo they can be ignored by presidents. And capital is not highly trained proffesional who knows what they are doing like a doctor (see Elon Musk) most likely they inherited that wealth. Even if they are, extremely rich people did not gather their wealth by being charitable, they are probably most greedy people and they will only act according to their interests
