Whether excessive medical tests or excessive surveillance, the minions happily promote it to ensure their job security. If the patient or the society suffers, well, that's okay. Perhaps a bit regrettable, but okay.
Ultimately, a society that strenuously promotes competition also engenders a mercenary attitude. So, you see, the excesses of Wall Street are not that far removed from the excesses of the NSA, or Microsoft, to pick but a very few examples.
The opposite of a correct statement is a false statement. But the opposite of a profound truth may well be another profound truth. -- Niels Bohr
