You said it yourself, cultural wars are just distraction to keep the elite in power and talk about everything except classes. People in power don't care about conservatives or liberals, they just pick a team and play the game.
By making immigration-without-visas a criminal offense, rather than an administrative one, the anti-immigration movement serves to drive immigrants (but not immigration) underground and makes their labor cheaper.
It's a lot like prostitution: since prostitution is a criminal offense, all prostitutes are criminals. They can be abused freely because they cannot go to the authorities without certainty being punished themselves.
By the same token, an undocumented immigrant cannot contact authorities to report they're underpaid, stolen from, beaten, imprisoned, or enslaved. (These are all things that happen regularly.) Their "criminal" status is used as a cudgel to abuse them.
Keep in mind, these are all people that just want to work in exchange for money, and they're responding to people and companies that want to hire their services. The "illegal immigration" posturing is just the buyers' way of artificially depressing prices.
- are severely uneducated. Consider distribution of political alignments in Academia. Consider the fact that antivaxxers and conspiracy theorists are in their overwhelming majority politically conservative and authoritarian. Belief in conspiracy theories is highly correlated with an impoverished interpersonal functioning, such as interpersonal paranoia, narcissism, disagreeableness, insecure attachment and Machiavellianism [1]. Impoverished interpersonal skills signify lack of empathy, which fuels dehumanization, and enables exploitation of others.
- grew up hammered by propaganda and the red scare, where anything that resembles social welfare is considered communism even if they themselves are dependent on such systems. Accepting that one needs help is exceptionally difficult for a person high on narcissism and paranoia.
Furthermore, when threatened, the brain takes "conservative" stances, i.e. stances that preserve the status quo. When faced with an ever changing world that does not resemble anything that they were accustomed to, they cling on to the closest sense of status quo even if the person or structure that supports it only does so for optics.
The lack of education makes it difficult for them to see that they are played like pawns by the bourgeoisie, that they receive preferential treatment through systemic issues [2], and finally they misattribute the reasons for their successes due to their obliviousness [3].

Kind reminder that I stated facts, so please argue, as adults :) .
Yes progressive values are a thing, but its media representation is nuts, on purpose.
The it's us vs them narrative leads to subjucating all values to pure "survival". This promotes long term irrationality. The powers at be know this and capitalize it. On both "sides". In my biased opinion this sort of Machiavellism is more common with conservatives, but its definitely common enough in non conservatives.
