Capitalism is failing because it is not subjugated to a relativity theory of freedom and thus accelerates its narrowing oligarchy. Any system is bound to fail when it is not subjugated to a meritocracy of freedom to constantly renew the system’s encroaching oligarchy.
So, capitalism as a concept hasn’t failed, yet our current vile-maxim implementation unhinged from freedom is guaranteed to fail spectacularly in due time unless we begin to subjugate it to real freedom.
