Economists of Scale is a great article in TCS Daily about why many economists seem "right-wing" or conservative. I think there are some good insights here.
So, viewed from Planet Liberal, economists do indeed seem to be right-wing. The above insistence that minimum wages might be a bad idea, the near universal agreement that unrestricted free trade is just fine and dandy, that immigration, while it does have some bad effects (sorry, everything has bad effects, it's the sum of all effects that is important) is on balance similarly a good idea…even the public choice theorist's insistence that government isn't actually a disinterested all-wise and all-knowing arbiter with only our best interests at heart. Actually, it's a collection of people just as self-interested and corruptible as you and I. These aren't tropes and memes that play well with those on the political left although, with the occasional exception, I don't think you'd find an economist who would reject them. Shades of difference in opinion, in how important they are, of course, but a general acceptance of the truth of the propositions.

In other words, if you study a science then it can't really be all that much of a surprise that you learn something of that science. And if economics is indeed a science then there are such things as correct answers, ones that will be recognized by all practitioners of that very same science.
