First of all, because I have read Marx among many other alternative views does not mean I am a Marxist. I think Marx is bloody brilliant in some regards but unfortunately he is correlated with regimes which were twisted out of control and not the classical definition of socialsm.
Interestingly I find much more value in ideas such as Tuckers "Individual Liberty", than anything Marx
Secondly, you avoiding alternative views including Marx, does mean that you don't have any ground to argue with anyone about it. Speaking of slavery - in your posts, you prove over and over again to be a slave to the mainstream by not being able to address anything except mainstream.
Thirdly, our "superpower status" was, has and is clearly impinging on others rights, globally, and any type of "super power" will is nearly always going to reflect negatively upon others - aka forcing ones will into someone else's lives who don't want it there, which in effect speaks against everything you are saying.
Fourth, "President Cain" WOULD in fact promote others being slaves - no different than what has been going on for decades.
Being a slave to business and corporate political leaders, corporate lobbyists, big banks, big oil...it goes on and on... Be it big or small gov't, if you are an American and you support people like Herman Cain and Perry and ROmney , you are a slave to mainstream politics no matter how large or small the government entity. And mainstream politics, beliefs and ideas are where being a "slave" to something begins - so deep engrained, you're officially are no longer thinking for yourself without even knowing it.
