The different forms of government and economic systems: Are there a few that just simply work best for our society, or do the myriad makeups of the various types of societies determine what systems are best for it?

Just wondering…....Because well…..you know, some feel ‘this is better than that’, but obviously what works for one country may not work for another, or may work better somewhere else etc.

I asked this as a social question because I am aware there is not a right answer, just looking for educated answers/opinions.
