So could you please explain this:

Millionaires pay no tax on the interest payments that they make on the mortgages on their second homes. Movie stars get to deduct the interest on their condos in Aspen and Congresscritters can deduct the interest payments on their DC condos.

No one considers this a threat to free markets or lists the distortions in incentives it created as a possible cause of our recent bubble and crash.

But now everyone is getting really worked up by the problems supposedly caused by not taxing health benefits for janitors and nurses aides.
