Fascism is the inevitable result of all government. Government is an accumulation of power, and it continues to accumulate power throughout its existence. Over the generations, it acquires more and more power exponentially.

Every self serving entity desires to accumulate power. The same can be said of anything that serves itself and can last beyond a single generation. A family, a commune, a group of like minded individuals, a business or a corporation, etc.

The goal should be for the organization to serve it's membership and for the organization's membership to include everyone. Capitalism's values and incentives are inherently self serving. Most capitalist "market theory" assumes, if not requires, self serving participants. Its an inherently self-destructive system.

That's exactly how Mussolini described it actually. Don't believe me, read the wiki
