What does the libertarian-minded Economist suggest for a country who is efficient at exporting nothing? Imagine, if they were all, also, hungry, at least a little bit. Then, by all rights, it would cost money to even get to zero in such a terribly poor country, therefore, it would be the last place on Earth anyone would invest.
Mr. Top Hat, meet Mr. Haiti.(Note: there are poorer countries, Haiti is the local/timely example)
