I once handled a case for a nursing home provider that was being criminally investigated for Medicare fraud. There was a big push by the Clinton administration to "do something" about the rampant fraud, which I guess has been going on since 5 minutes after Medicare was enacted.
Apparently, these facilities don't bill Medicare for each service or occupant, but rather bill Medicare for their overall expenses -- all electricity, water, employees, rent, etc. Naturally, these global operating expenses just go up and up and up, and they hide all sorts of little extra expenses that the facility operators can bury in the account statements.
In my little case, the result of the federal investigation was the discovery that the business manager of the facility had deposited money into the employees' retirement fund a few days later than scehduled, on three occasions, for a total of about 9 days of delay. As a result, the retirement fund lost about $80 that it otherwise would have earned if the deposits had been made on time, although Medicare was billed for the full amount, including the extra $80. It cost the client about $50,000 in legal fees, plus the time of the G-man investigator and a team of forensic accountants, to uncover this Crime of the Century.
Being government investigators, they had no price signals to know what they ought to pay to chase an $80 accounting error. It cost them nothing to spend their time on this matter.
Meanwhile, Medicare was paying the facility about $500 a day for each patient's room, which you could get anywhere else in that area for about $500 per month. Medicare paid for all the elder care services and employees and supplies on top of that. That fraud was perfectly legal, however, according to the Alice-in-Wonderland world we live in.
It was then that I realized I was in the wrong business.
“I do not ask that you place hands upon the tyrant to topple him over,
but simply that you support him no longer; then you will behold him,
like a great Colossus whose pedestal has been pulled away, fall of his
own weight and break into pieces.”
