Vejam como este parágrafo de Principles of Economics (Gregory Mankiw) tem tudo a ver com o post anterior.
"To say that the government can improve on markets outcomes at times does
not mean that it always will. Public policy is made not by angels but by a political
process that is far from perfect. Sometimes policies are designed simply to reward
the politically powerful. Sometimes they are made by well-intentioned leaders
who are not fully informed. One goal of the study of economics is to help you
judge when a government policy is justifiable to promote efficiency or equity and
when it is not." (p. 10)
Não falei que os caras não estudam economia?!
