Capitalism doesn't have a purpose any more than, say, evolution. Capitalism is, perhaps, best thought of as a description of how the world works, in particular, how wealth is created. It has nothing to say about why wealth is created any more than evolution has something to say about our purpose for being here. Attributing purposes to properties of the universe is the domain of religion. Thus, I think it would be safe to say that everybody is a capitalist; some are also beggars or thieves. To call Thiel a "capitalist/investor" says more about you than him. You seem to be pushing your particular religion and are accusing him of being an atheist who could see the truth, but for the mote in his eye.
