Why wouldn’t communism lead to cancer like growth? Wouldn’t political leaders be incentivized by the masses for never ending quality of life improvements?
Money is not the problem, it’s people. If replace the system, nothing changes. If we want sustainability, that needs to be desired by the masses, and that is achievable without communism.
The Soviet Union threatened my parents and grandparents lives. My country did try it, we decided against it. All the issues that capitalism has, communism still has. Add centralized power, and human exploitation is worse. Communism will not solve your problems.
