Found in my files, but timeless:
August 8, 1997, Washington Post story on medicare fraud... Billions are taken, all by prosperous and (to take a wild guess) Republican folks. Dwarfing not only all welfare fraud but, perhaps, all welfare. Turns out it was childishly easy to defraud Medicare. No doubt investigation would show that the Republicans and Republicrats were behind efforts to cut enforcement in this area, as in so many others.
Conservatives are hell on wheels for law enforcement in those areas where the laws are broken by the poor, such as dope and street crime. But they consistently oppose hiring more cops when the request comes from HHS, IRS, EPA, NLRB, SEC, and so forth. Which is to say in those much more lucrative areas of crimes which are largely committed by Republicrats themselves. In those cases it becomes not law enforcement but government interference.
