As a former (briefly, due to an acqui-hire) consultant at one of the big companies mentioned, this was a really interesting read.
I never thought anything the company did was morally wrong per se, it was just a different business model that I didn't really want to be a part of. The role of most people in the U.S. was landing the big deal, talking the client down when things went wrong, and then winning an extension for additional services at the end. Actual implementation was just a cost to be minimized and handled somewhere at one of the company's offshore sites. Somehow it all worked out (usually) even for some truly massive projects.
