Capitalism is not an ideology. Neither is it an economic theory. It is the natural system of the exchange of goods and services among a free people.
Socialism is an economic theory and shall forever remain so because it has never been proven to work.
Democracy is best described as mob rule. The words democracy, democrat, and democratic appear nowhere in our founding documents and for good reason: all democracies eventually self-destruct.
Our Founding Fathers crafted a brilliant social compact we know as the US Constitution. This social compact recognizes the fallibility of all mankind. This is why we have accountability and personal freedoms inextricably bound together and no single office holder capable of controlling our people through his or her dictates.
