So, you're telling me I should, what? Voluntarily make my life more difficult to make sure I live to 90 instead of 70? Naw, I'm good. I don't believe there has ever been a system that "consumes too hard", simply systems that allow corrupt, incompetant people to weasel their way into positions of power, use them exclusively for their own benefit. When they get called out on their corrupt incompetence they make up nonsensical excuses like: "consuming too hard (as if they aren't the ones actually guilty of such a thing), or "too many people, gotta treat people like cattle and cull the herd."
When, in reality, competent people would have no problem managing resources, but that prevents the corrupt, incompetent people from getting the power they lust after. That is to be expected from any human system. Free markets simply allow for alternatives to compete against the failures caused by incompetence, so the system can self-correct, which it has and will, just usually with dire consequences. But that's the fault of corrupt, incompetents getting power they shouldn't have, not simply a flaw in the system.
