Some analysis of the 2017 General Election in the UK has been published in the Financial Times, which seems to indicate that people without a university degree, who were working class, and had poor health. Were more likely to vote for the Conservative party (who are politically right wing). Indeed throughout this election campaign polling seems to indicate that working class voter tend to vote conservative.
This phenomenon however is not limited to the UK, in 2016 non-college educated and blue-collar workers flocked to support Donald Trump and the Republican Party. Although the point surrounding Trump could partially be talked of as a backlash against globalisation etc etc and that, it's undeniable at least that at least some portion of the working class electorate are inherently on the political right

Who was perhaps one of the farthest right candidates to make it to the 2nd round of the French Presidential s.
Now I'm looking at this from a British perspective, but "left-wing" parties in the UK such as the Labour Party, started off as the "workers" parties and were initially at least almost exclusively voted for by the "working-class". Working class interests were at least theoretically served best by left wing parties e.g. setting/raising the minimum wage, Universal Free healthcare, the welfare state, social security etc. Indeed left wing policy on paper at least seems to serve the working class better, for example several of the Labour party flagship proposals such as abolition tuition fees and cutting zero hours contracts and increasing the minimum wage were in the direct interests of working class voters who wanted their children to go to university with reduced debt, who were on the breadline and needed job security, so why are the working class moving right? Why are they voting against their own (theoretical) economic interests?
