They're not ignorant of it, they simply don't care. They don't care because the public good is not, never has been, and never will be, the primary goal of politicians and bureaucrats. They spout "economics" rhetoric to support the policies they want because it helps garner support from certain sectors of society. They only do that because, in a representative democratic system, they need to maintain support else they will lose the power to do what they want. So the solution should be obvious (which doesn't imply that it's easy).
