We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Give us more power because we understand the world better than you do, was the message. We are so smart, so well-credentialed, so careful to read all the best papers by all the certified experts that the recommendations we make and the regulations we write, however outlandish and burdensome they look to all you non-experts out there, are certain to work. Trust us because we are always right, and only fools and charlatans would be so stupid as to disagree.
Mr. Mead still seems to miss the important point as to why us peasants don't trust them. Earlier in his piece, he acknowledges that sometimes they get things wrong, and that it is not usually worth pondering on. It seems he thinks the only failures worth pondering on for the left are those that effect their own lives, not those they are supposedly advocating for. When welfare doesn't work, it isn't worth pondering on, because Mr. Mead is not on welfare.
Only things that effect a liberal's own life are worth a liberal pondering on when getting something wrong.
