What is Working Class?

I always presumed that culture and activity overlapped a lot. My dad was a labourer from a poor Irish Catholic large family who grew up in a poor inner city. Beyond 16 no education. My mom came from Oxford, was well educated, taught languages, grew up with a middle class journalist father. The Monty python sketch "every sperm is sacred" juxtaposes these stereotype cultures of poor Irish with lots of kids and small British family that is educated. American leftwing ethnic class divides carries over very well here into the UK. In America where I grew up my parents did not talk politics or religion. I assume he voted Dem and she voted republican. My education is higher but practice is now working class. My ideology is fluid depending on the issues. If the left only care about gender rights and minority quotas then obviously this does not have anything to do with unions, helping the poor. It should be color blind. Poor workers are in rural and urban areas. Trump and European neo conservative parties are using the left's progressive message which targets privileging identity over income as a no go. If people are jailed for critic of this then obviously we have a democratic deficit. Excessive nativism was repeatedly a historical problem in America after large waves of immigration, resulting in a crackdown on this. This has been now repeated and Europeans should see this as normal. If Europe is an immigration center then it has to be managed sensibly. If the working poor natives feel disadvantaged by the left then they will vote right, even if those parties are against their pocketbook. The left was traditionally for the poor. When you introduce the foreign or racial element, as in America with quotas or special advantages for blacks in public job applications or universities then it is clear that a conflict will emerge. Eventually leftwing parties simply could become a racial party. This would be like somewhere in Africa or Indian politics where ethnic representation to get govt jobs and funding is all important and the class concept disappears entirely.
