The outcome of our economy shall not be held hostage by confounding of consequence and cause.
First, socialism is alive and well in any country that fails to define and adhere to the operating principles of the freedom of freedom (a relativity theory) and a meritocracy of capitalism that depends on such freedom.
The point is that all economies today harbor vast amounts of socialism, defined by me as the overwhelming conformance to our similarities. But countries deploy different flavors of same, some socialism more oligarchically rather than government-controlled.
Capitalism, without the operating principles of a meritocracy, in violation of the most basic definition of freedom, is merely oligarchically controlled socialism, different and less transparent to the general public, but equally harmful nonetheless.
The only reason why capitalism in its malformed constitution still wins out is that amongst the other systems you mentioned, it is most capable of producing outliers to obliterate its failings from the past, albeit at a significant cost of those who are not.
To end on an up-note, the outcome of our economy is not as feeble as we think, because the only thing we need to change is how we value our creative differences.
