The economist’s fundamental assumptions are wrong. The free market rational actor model is wholly incompatible with the ability of a finance or marketing industry to exist because marketing could never inform or convince anyone of anything and contracts can provide anything financialisation does without giving 10% of your income to someone who did nkthing. Given that both exist and together dominate the industry of the wealthiest countries, we know that none of it is real, and that the people pushing it also know this.
Psychology and physics are founded in empiricism, not post-hoc rationalisations of what the powerful wanted to do anyway.
