Nice article. "This willful ignorance isn’t surprising because politicians love giving big handouts to small numbers of people by nicking a small amount from big numbers of people." In Economics terminology/buzz words: politicians love doling out 'concentrated benefits with diffuse costs.' The low cost incurred by any single individual creates a 'collective action problem.' The same predicament was addressed in tort law by allowing class action lawsuits.
So, you can use this jargon when addressing economists. Of course, these days they are more devoted to adding to the wealth of their paymasters than of understanding how things work, so don't expect to induce much comprehension in them.
