@Gue: You never specified that. And what you proposed is not making the optimum number of people happy. It is making the optimum number of individuals in certain groups happy. There is a vast difference between the two. As such, I am even more against whatever type of government you now propose simply because to have the minority rule the majority is just as bad as having majority rule the minority.
Basically, what you propose cannot exist unless your statement "having the optimum number of people happy" is rephrased to "having the optimal number of people from specific groups that I choose happy." In the latter case, you can succeed. In the former, under your restrictions and what I believe from your comments is your perspective, you will inevitably fail.
Personally, I think the best system of government is one modelled after a combination of the government styles of Israel, Great Britain, and the US, with certain Old Testament principles such as the institution of the Jubilee and Sabbath Year included.
For those who don't know what the Jubilee and Sabbath Year are, I'll explain later - it would take too much work right now, and I have a lot of schoolwork to do.
@ Irtar: I completely agree. Except I don't recall mentioning Jesus in this thread, or anything about the Bible for that matter except in this post (and then only by way of mentioning a system of economy that I think would work well).
