I think conservatives are wrong to complain about Obama making a recess appointment of Gary Becker to the National Labor Relations Board. If he had appointed John Stossel when Congress was in session I would be (almost) equally outraged — since the NLRB is illegitimate to begin with.
Tragically, the descendants of the Wagner Act and other pro-labor legislation continue to pollute the economy. Repeal all of it and we can forget which particular communist happens to head the NLRB at any given moment.
Just say "ix-nay" to all the pragmatic arguments about getting "our kind of guy" to head an unjustified Federal organization. That didn't work out so well with Greenspan at the Fed and it doesn't work anywhere else.
