My micro/macro courses used Hubbard's book. Wasn't he a Republican economic advisor? I recall picking up on his bias in the edition I used pretty often.
Yeah, there's one section where the authors talk about why the US has a higher per capita GDP than other developed countries, but fail to mention its vastly higher inequality compared to other developed countries. It's one of the things that's technically true but very misleading.
I don't think that it is. Many left-wing people still hold some right-ish economic views; for instance, that growth is an important goal, that we should aim to keep deficits low, that money—and not resources—somehow constrains governments, that there is a "natural" rate of unemployment, that market failures can usually be solved with market solutions, that free trade deals are good and that "protectionism" is bad. More generally, there is a tendency, at least among academics and pundits, to talk about "the economy" as if it is some abstract, mathematical entity separate from the rest of society. This view facilitates and justifies right-ish economic policies, like austerity, exporting manufacturing to Bangladesh so we can have $3 t-shirts, etc.
Maybe you see things differently (and I very well could be wrong), but it seems to me that the right is winning the battle over economic ideology.
There's actually some research on this, and political leanings break down by sub-field in the way you'd expect. Financial economists are on the right end of the spectrum. Macroeconomists are fairly centrist. Applied microeconomists lean hard to the left. So fiscal and monetary policy - the stuff you hear about in the news - tends to come from more of a centrist to right-wing perspective, whereas advice on social programs - the domain of policy wonks - comes from the left.
Of course, implementation is a different story, being constrained by politics. Politicians - especially in the States - lean far more to the right than academics. The end result is a lot of "best-case" policy within pretty conservative constraints. See, for example, the PPACA, a veritable Frankenstein's monster of legislation that exists only because of the political situation in Washington, when a public system (with small fees or copayments) is probably what most economists would endorse.
Bottom line: the average economist is right-wing compared to the average academic, but slightly left-wing compared to the average person.
If you don't mind my asking, are you at a freshwater or a saltwater school? That might explain our differing perspectives.
