So, Jagdish Bhagwati, an eminent economist, writes a piece on the myths and costs of protectionism. In the comments we get:
Professor Bhagwati is an economist, of course, and his views should therefore be taken with a very large pinch of salt.
That is, we shouldn’t listen to an economist talking about economics because….he’s an economist.
This is also good:
Jagdish Bhagwati has academic tenure, and therefore a job for life, with zero risk of being replaced by some academic from the third world who is prepared to do the job for a fraction of what he’s paid.
The Good Professor of course being one of those academics from the third world.
