I would expect other systems to optimise/maximise other things, the current, especially in the US thanks to lobbies and borderline corrupt politicians + conflicts of interests, maximises wealth acquisition and cost reduction without any regard for health or long term effects

It's really similar to the tobacco industry back in the days, and will probably end up the same way (fingers crossed)
