Barbara J. Stewart may be onto something here. Consider:
(a) Wal-Mart requires cut-rate slave labor to continue aggressively exponentiating its vicious circle of supply and demand;
(b) Third World nations currently offer the cheapest source of sweatshop labor;
but:
(c) a significant percentage of the America population is in prison;
(d) the prison population's toll on the American economy is immense; and
(e) federal and state governments continue to outsource more and more of the day-to-day management of America's incarcerated population to private companies.
The solution is so obvious, then: let Wal-Mart take over America's prisons!
It'd be like the great lost Philip K. Dick novel.
