Please do not confuse capitalism with central banking and the fractional reserve system. It is completely anti-capitalist; capitalism is about free-markets and having a monopolistic central bank is completely anti what many libertarians and true capitalists want.
Central banking in fact, is a central tenant of Communism if you read Marx, as he says it allows control over the financial services and economy. It is to this principle which many modern-day liberals and socialists still aspire.
The problem with this is, as we see now, even if you have this liberal/socialistic type of government; central banking in itself creates and allows the maintenece of a super-rich elite to run it. This is where we find ourselves today.
This alternatives are; a resouce based economy as in the Zeitgeist movies (however I personally am skeptical how the transition could be made tomorrow, if a vast change was to happen), a libertarian type of free market world (which could mean the vulnerable suffer), or a JFK style capitalist state, with a none fiat currency central bank (however he got assasinated for trying to set this up).
Calling it a capitalist conspiracy is wrong, central banking and capitalism are opposite concepts.
