As I mentioned a little while ago, if “working class” is defined in terms of income (the same is true, I think, for self-description) rather than the lack of a college education, the “white working class” in the US is about evenly divided between Democrats and Republicans. Lots of commenters made the point that this split varies sharply by region, and this has been confirmed by Kevin Drum and John Sides who cite recent research from the Public Religion and Research Institute. Using the “non-college” definition, they point out that the Repubs have overwhelming majority support from white working class voters in the South (as they do from white Southerners more generally), but that for the rest of the country, “working class” whites divide evenly between the parties.

In other words, if it weren’t for the South, the US would be a lot more similar, in this as in other ways to other developed countries. Conversely, from the Southern perspective, large parts of the US are, indeed, more like Europe than like the America they know and love.
