Why would this even be so. It's not magic it's just people doing stupid people things often to maximize short term factors. It only gets long-term planning insofar as embedded agents do. One of the things agents do is use incentives to inspire behaviour that is conta individuals short term incentives to achieve behaviour that contributes to long-term success.

Not only are many individual agents aligned with short term interests they often either can't because they will be pushed out by short term thinkers or literally benefit from net harm to all. America mostly being composed of the rich not the masses voting with their wallets.
