It would be reasonable to think that a densely populated island with exorbitant land and housing prices would be happy to alleviate its crowding problem. That's not the thinking at the Washington Post.
The Post had an article this morning noting the surprising fact that the number of obstetricians in Japan is declining along with its dropping birth rate. The article notes that Japan's population is currently shrinking, and that if current trends continue, its population will fall from over 127 million to just 100 million by 2050. The Post then describes this drop in population as a "problem."
Well, fewer people, rising capital labor to ratios (and therefore higher wages), less crowding, and less pollution is not a problem in any economics I know. Maybe the Post will explain its reasoning in some future article, but for now, this front page story simply doesn't make sense.
