What Government Funded Should Science Do?
Firstly, i guess i should state the role that i see appropriate for the government and funding scientific research. That role is... nothing. Taxpayer dollars should not be spent of scientific pursuits (unless these pursuits can be shown to make money for the government). Humans have a natural curiosity about them, about the universe and their place in it. Science can give answers, but at great cost (especially financially).
Think of it more in an investment model - only pay for things that financially enrich the country. This would mean that a group like NASA shouldn't send up shuttles/rockets (at great expense) for missions that are just a cash drain. Missions with real money on the line (like deploying satellites) might make sense if the cost of the mission is covered by the revenue from the mission. Planning a manned exhibition to Mars would be a waste of resources that would be better used elsewhere.
Some amount of scientific research may be needed for certain government agencies, like maybe the CDC and FDA, but should be limited to what is strictly necessary. Science should advise, never rule. The highest paid government employee should not be a scientist - even if he thinks he is "science".
