Socialism is a symptom, not a system.
And socialism is omnipresent in any environment in violation of the most rudimentary principles of freedom. In a more capitalistic environment, void of the tenets securing a relativity theory of freedom (real freedom), socialism is more oligarchically controlled, as opposed to socialism instituted by the government in less capitalistic environments.
Surprising amounts of oligarchically controlled socialism impregnate all of our systems, hence the reason for our troubles. Examples are our economics, the stock-market, governance, political process, “free-trade” agreements, health insurance, education, etc.
We, in the U.S., succeed despite not because of the systems that attempt to hold us hostage. A reason why we should be in awe of the people of this country, its leadership not so much.
