Yes... PURCHASING managers, NOT manufacturing managers.
The survey is skewed by these companies taking full credit for their finished product, despite ever-increasing proportion of foreign componts that are purchased rather than manufactured domesticly. As our Trade Deficit races to astronomicly absurd levels, the ISM stats continue to give a distorted perspective of "manufacturing" that is rapidly morphing into mere warehousing and distribution.
The secret within capitalism is the wealth generation inherent in what Adam Smith calls "The division of labor," where, for instance, finished cloth is produced by machines that have replaced labor intensive devices such as spinning wheels and hand looms.
It is that creaton of wealth inherent in capitalism that makes nations wealthy -- that makes nations able to buy more than they sell (a "balance of payments deficit") -- that essentially blesses people within that nation.
