Ruth Marcus in the Washington Post today says that the real scandal with the IRS' targeting right of center nonprofits is that the IRS hasn't been doing its job monitoring all 501(c)4s and letting them get away with huge violations. Anecdotally this may indeed be the case but I for one certainly don't have enough evidence to support this claim.
Meanwhile, another area where one might question the IRS' effectiveness: churches -- really big ones in particular -- you know those corporate (and yes, perhaps the Roman Catholic Church should be included) who do all kinds of things political and pay really huge salaries to the chief ministers and if not in cash, certainly in life style.
Ah, but perhaps this, not unlike the 501(c)4 situation is more of a public policy question, not the question as much about a governmental agency not functioning very well. And the public policy question: who should be tax-exempt and for what purposes and with what restrictions. Perhaps it is time to re-open this can of worms.
P.S. Nonprofit boards -- maybe now's the time to start adding these questions to your agenda and forming an opinion and a strategy for what to say to your legislators.
