Capitalism is a subset of Individualism

Capitalism is not Republican nor Democrat for their preferred ism is Cronyism, a close cousin to Fascism (see note). Since both major parties are equally pro-Cronyism, both are equally pro-Socialism and pro-Militarism, consequently, both are equally anti-Capitalism therefore anti-Individualism.

Capitalism is a subset of Individualism. To expand, it is the liberty to wholly maintain what you earn and barter, to freely consume or use as preferentially determined as well to freely invest (what is not consumed or used) in your own endeavors or the endeavors of others upon unanimous consent.

Capitalism is merely within the Singular Human Right to Consent or Not Consent on all matters; sexual or intimate, family, private, social, religious, public, political, and more, including economical that intertwines with all other activities.

Note(1):
First and foremost, Fascism as well Communism are political systems seeking 100% control of the economy from opposite directions. The former by "top-down" enforced control per taxation and regulation, the latter by bottom-up enforced control per confiscation thus nationalization. Thus death camps, holocausts, ethnic cleansing, mass executions, and more, are all possible outcomes or characteristics of tyrannical isms, not the foundational definition.

Come let us Reason (Is 1:18). Peace is always a Choice (Mt 5:9).
