Are Republican and Democrat parties just two sides...?

I didn't have to watch the video to agree with the premise you advance - to some extent, at least. It is simply a fact that while there are differences in which token 'causes' either will advance while in power, both are guilty of conspiring to shift power from the people to the government. They do so in different areas how and where they can, but the quilt they are sewing together has one purpose: to regulate (and suffocate) the once free, gasping population under their rule.
