What Is Seen and What Is Not Seen

The words of Frederic Bastiat are always on my mind here.

"In the economic sphere an act, a habit, an institution, a law produces not only one effect, but a series of effects. Of these effects, the first alone is immediate; it appears simultaneously with its cause; it is seen. The other effects emerge only subsequently; they are not seen; we are fortunate if we foresee them.

There is only one difference between a bad economist and a good one: the bad economist confines himself to the visible effect; the good economist takes into account both the effect that can be seen and those effects that must be foreseen."

Here is a question. Does the city of Pittsburgh generate lot's of bad economists or lots of good politicians?
