Walter Pincus argues that, in addition to being unaccountable, private military contractors are much more expensive than professional soldiers:
According to data provided to the House panel, the average per-day pay to personnel Blackwater hired was $600. According to the schedule of rates, supplies and services attached to the contract, Blackwater charged Regency $1,075 a day for senior managers, $945 a day for middle managers and $815 a day for operators.
An unmarried sergeant given Iraq pay and relief from U.S. taxes makes about $83 to $85 a day, given time in service. A married sergeant with children makes about double that, $170 a day.
