Other Separations of State

People talk about the separation of church and state. That's fine although that phrase was never in the Constitution. Basically that means the gov't cannot create a state-owned religion. If that happens then you have the church elders basically endorsing whatever beliefs the gov't has right or wrong. The first amendment does not mean politicians cannot be moral or have religion. That would dangerous and ludicrous. Since power corrupts I would think you would want the most ethical politician you can vote for.
But I think there should be other "separations" like:

• The separation of business and state. Gov't should not be choosing winners and losers by subsidizing businesses it likes and over regulating businesses it doesn't like. That's the free market's job to choose winners and losers. Once you have crony-capitalism then have businesses attempting to influence Congress for their own benefit.
• The separation of science and state. Gov't shouldn't deciding what is good and bad science by funding a specific research program. When does that it shuts down almost all other avenues of research on a particular problem. In dictatorships, science becomes another part of its propaganda machine. It uses science to justify whatever beliefs it has about nature.
• The separation of the fine arts and state. You want gov't deciding what's good and bad art? In dictatorships, the fine arts become just a propaganda tool (think of the statue of Saddam Husein) and whatever art it deems offensive or critical to the state (read: the dictator) it bans. There is no need for the National Endowments for the Arts.
• The separation of education and state. When the state takes over the education system it becomes indoctrination. Education should be controlled at the local level.

There could be other separations but these are the main ones.
