This is a repost of a blog entry from February 2009.
Ran across this during my reading:
Where one nation has got the start of another in trade, 'tis very difficult for the latter to regain the ground it has lost; because of the superior industry and skill of the former, and the greater stocks which its merchants are possest of, and which enable them to trade for so much smaller profits. But these advantages are compensated, in some measure, by the low prices of labour in every nation that has not an extensive commerce, and does not very much abound in gold and silver. Manufactures, therefore, gradually shift their places, leaving those countries and provinces, which they have already enriched, and flying to others, whither they are allured by the cheapness of provisions and labour, till they have enriched these also, and are again banished by the same causes. And in general we may observe, that the dearness of every thing, from plenty of money, is a disadvantage, that attends an established commerce, and sets bounds to it in every country, by enabling the poorer states to undersell the richer in all foreign markets.
-David Hume, Of Money- 1752
