Is Simple Cost Benefit Analysis Too Difficult for Our Government?

Does anyone in Washington, DC understand the concept of using cost benefit analysis to determine what the best use of our tax money is?

For example is spending trillions to fight wars supposedly aimed at neutralizing maybe a few hundred fanatical terrorist criminals with no actual country affiliation, who once killed 3,000 Americans in a terrorist attack who might be able to repeat such an attack someday, a higher priority than spending the same money on providing health care and other vital social services to those in true need thereby saving hundreds of thousands of lives and improving the lot of millions more suffering illness as a result of being uninsured or under insured?

Looking at the numbers the answer is rather obvious but Washington doesn't get from point A to point B in a straight line. It zig zags all over the place so many special interested parties with too much influence over politics can make more money and gain more power. They do this by creating a bunch of irrelevant arguments between our emotional citizenry aided by their vociferous pundits playing on our fears and prejudices based on inflexible ideologies to distract the citizenry from the simple solutions.

This country is rich but we piss money away stupidly by the hundreds of billions every year on maintaining troops over seas in places like Japan and Germany etc and on offensive and defensive weaponry that will never escape the warehouse, We continue to do this while our infrastructure rots and social problems right here go unattended! So citizenry, keep arguing over political, religious and social ideological differences like the special interest minions want you to do while they rob us of all our money and say about issues and in about ten years look back and see how much worse the situation has become except for the few corporate giants who have gained more wealth and power over the rest of us poor slobs!

We need serious campaign financing election reforms and restrictions on lobbyocracy influence before this government can reform anything in a rational manner and before it can function in the best interest of our citizenry in any way that resembles what the framers of our unbelievably farsighted and wisely conceived constitution intended.
