The way the fraud works is different. In the US it is their insurance is good, keep them in. In Portugal everyone has the same insurance so it is keep our faucility as full as possible, only releasing just enough people to make it appear like we are doing something.

I have no idea what fraud occurs. In either system. I know enough humans to know that some are honest and some are not. Thus if it is possible to get away with fraud odds are someone is.
