You also have issues where high-school educated men have not seen any major benefits to any typical liberal or conservative ideology within the past generation.
On the conservative end, the jobs that the men would have gone into have seen wages and benefits stagnate or drop.
On the liberal end, the status of white men in society has dropped to a more level playing field with class status or wealth being a more defining factor, something which they don't have.
Alt-right conservatives are addressing the economic issues by restricting the work force (anti-immigration) and increasing the jobs in resource extraction (trashing all environmental laws). On social issues, the alt-right head of family is the man.
