Russel Roberts sintetiza en un párrafo una diferencia fundamental entre quienes confían en los políticos y quienes confían en los empresarios: unos se fijan en las intenciones, los otros en la estructura de incentivos bajo la que operan.
[A]t one extreme you have non-economists who trust politicians because they say they are serving the public, but who distrust businesses because we know deep down that they really only care about profits. The economist answers that talk is cheap. Politicians are self-interested. So are people in business but because there is more competition in business relative to politics, businesses often do a better job of serving the public than politicians do.
