This writer stupidly stumbled onto a critical point: oil "wealth" is purely extraction. Oil can be a wonderful commodity, but like gold is USELESS unless employed toward an increase in standard of living. This is accomplished but taking the money that is generated by the oil and INVESTING it into businesses and firms that make products that SERVE people.
This is something almost none of the Arab oil states have learned. Their oil will run out, just as Spain's New World gold ran out---and when that happens you better have created a wealth PRODUCING economy rather than a wealth EXTRACTING economy.
BINGO - We have a winner.
