I think these days "wingism" is more to do with social attitudes, which is why we keep seeing attempts at stirring up a culture war. I associate racism, jingoism and a belief in meritocracy as a holy grail as right wing. Right-wingers tend to believe in law and order - until it applies to them. They resent having to share their wealth and dislike anybody telling them what to do, which us why they dislike the power of the state.
It hasn't always been the case, when there was a much clearer dividing line between the "traditional" blue collar working class and property owning farmers and those with inherited wealth. The Industrial Revolution created dividing lines between factory/business owners and landowners - of course, most people didn't have a vote until the early twentieth century. There were various pro-worker groups and those with liberal views, but they didn't have any political power until the twentieth century.
It's not surprising that workers supported the new parties, but these days many of the old dividing lines have become blurred.
