You could actually make a case for just about every western government being economically right wing as the PC basically does, but it uses some very clumsy logic. If one has an economic spectrum consisting of North Korea/Khmer Rouge style collectivism and total government control on end and Rothbardian anarchocapitalists and the Galt's Gulch type society on the right, the Scandinavian style social democracy does kind of seem to sit in the middle. But this is a really stupid spectrum to use as a measurement. To simplify it even further, if one argue that 100% of the economy be government controlled is the leftmost position and 0% is the rightmost, and thus 50% of the economy being government controlled is the center, then even Nordic social democracy would be right of center and someone like Hugo Chavez as an actual centrist. So using that standard then yes the Democrats and European conservatives have little distance, but there's also little distance between the Republicans and European left wing parties as well relatively, and they all sit on the right. But it's quite obvious why that's such a ridiculous model to use.
First and foremost, because the idea of government control of the economy being the fundamental criterion for being left-wing is nonsense.
