From personal experience with some of them (mostly older, working class white men, but not that much older...I'm talking like 45-60 years old) I can say the whole problem, according to how they've gone out of their way to explain it to me, is they're owed whatever perks they get out of life because they work for them and you don't. I've had them tell me so with a straight face even while I was "working for it" just as hard as they were, no if, ands, or buts.
Pointing out I am (or have, or was, or will be again, depending on my situation when we had these conversations) "working for it" just as hard as they were would only lead them to point out that if I ever qualified for or used government entitlements to do anything, like not die of a tooth infection or perhaps not starve for lack of food, then I'm lifelong disqualified from ever bothering the hard-working Murcan taxpayers again.
Simple as that.
I've often wondered how when my work history gets put up against theirs, mine gets erased on the spot for having been supplemented at any point in time. I can be working, but if there's even a whiff of an EBT card on me as I walk by, I'm disqualified from having any perks of American life, like eating or not dying for lack of funds to pay in full at time of visit, so I should go quietly lie in a gutter so as not to bother hard-working folks like them who deserve better than to subsidize me.
Not only am I disqualified, but they want everyone to know they're getting robbed. Not just by me or people like me who've ever leaned on their hard-working taxpayer dollars for a single moment, but by everybody. It's classic that everyone's using them for something: Their employer's using them by overworking their bodies, minds or both for too many hours and not enough pay; their government's using them by making them pay a single dime in taxes for anyone else's existence; everything is described in terms of their financial martyrdom to others.
They keep paychecks to themselves even if their wives or SOs aren't working and have little to no other sources of income; tend to overspend on their kids, then complain the kids are taking advantage and aren't turning out as hoped; tend to overspend on themselves and not week by week, but day by day, then claim it's only because they deserve to have nice things for all the hard work they do and the upholding of the American welfare state that they're personally financing. Not you. Them.
Then they'll complain of being unable to buy groceries or their next beer or whatever, not before another payday rolls around (when it's just Tuesday) and I'll think to myself, "You said you "deserved" all this high-life horseshit; I see where it gets you" because another thing is they seem to think they're rolling in dough even if they make maybe less than (or at most) $20 an hour, yet they talk - and spend money - like the gold-plated toilet is in the bathroom right in back of the living room in their trailer with the 70-inch financed TV hanging up on the wall.
I don't know what drives them. They're usually too incoherent and/or emotionally chaotic to get to the bottom of that. I prefer it when people state their rationales calmly, clearly, sans overly-divisive emotions, but these folks can't do any of that, because their emotions carry their rationales clear out into the Twilight Zone faster than you can hope to know why. I don't know if right-leaning women act or live similarly, but even when I've known these men's spouses, they were polite enough to not quite batter me to death with their opinions - then again, I'd catch them using more bigoted language and higher-strung defenses than the men did in private conversation that did not involve, or include, me.
These men I'm speaking of also had or have randomly volcanic tempers (the worst kind, in other words) and were usually in the throes of strongly denying being wracked by multiple addictions, so whether their other halves went along out of fear of riling them or out of a genuine shared hatred and a feeling of being put-upon and used by the rest of Murca is or was not clear.
Where I'm going with this is, I see a lot of people try to explain the cruelty of yanking people's insurance or Medicaid (or at other times, welfare or food stamps) by saying their thought process must go something like this: "I got mine, so screw you". But that's not entirely it. It's some, but not all of it.
It's more like: "I got mine - and I worked hard for it and the rest of you didn't, or wouldn't if given the chance - so screw you". I can't overstate how martyred they are over having to go to work each day, and pay taxes, and not go fuck up the rest of Murca for putting them through so much for so little, because Murca is literally (to their minds, and to a person) financed on their backs, and their backs are hurtin' so they just want to sit back and collect like "the rest of y'all do", but "you" are "sucking off" them, so they can't* (more on that at asterick).
So if you can't afford health care then that means you either aren't working (or aren't working hard enough), weren't working (or weren't working hard enough) or might not work in the future (or might not work hard enough) and you'll never work as hard as they do, because no one does, so you don't deserve it. They've paid for you long enough, and will pay for everyone like you long enough, so screw you, because they got theirs and they shouldn't have to pay for yours.
I'm mentioning this so you'll get why some working class people (and working class white men, in particular) vote and even literally think in ways that clearly work against their own interests: because their perceptions are skewed in unhealthy and even hateful ways, though they don't see it as hateful so much as they see themselves as taken advantage of by nearly everyone, and especially by the poor. Of course, their self-regard doesn't match the reality in any but the most passing of ways, but let's not let the truth get in the way of a good story, as I often told them, myself. :)
For another, I'm trying to gird people for when the Senate not only rams their Wealthcare bill through about one second past midnight July 5th (or whenever; every time I check the deadline changes again), and then all your working class neighbors erupt in cheers and threaten to wipe every last poor off the face of the Earth if they don't go and just fucking die of something already. Expect both things to occur pretty much in tandem. It's not just rich, white men who want it this way: it's some of their lower class cohorts, too.
We could get into "why" but in fact, another reason I'm posting this is for the sociological aspects of it that might be studied or looked at by others. I want to spread as much fodder as I can and this post adds a little to hopefully figuring out what makes the more cruelly right-leaning tick, though I can't explain much of that myself.
I can only tell you what I know: the few I'm acquainted with aren't thoroughly educated but seem to know everything; have mostly dead-end jobs; not only expect but often demand that their opinion be deferred to; claim they're not prejudiced but complain of every non-white, non-citizen and non-binary group "taking advantage" and "working the system"; have poor attitudes toward women, LGBTQIA, immigrants and non-whites in general; watch FOX News, rock multiple addictions, and have had either missing or exploitative and cruel fathers. Maybe the last two (multiple addictions; bad fathers) are not the norm for most right-leaning people, but either way I'm throwing it out there.
The last part (bad fathers) makes me think they grew up seeing themselves as victims, so the idea that they're being victimized by The Other somehow naturally gets woven through their lives. But with or without any benefit or perk from working, their attitude remains the same: they finance Murca, you don't, so go away.
*Oh, but yes they can. Let's check the hypocrisy of them spending their whole lives shoving anti-poor militancy down everyone's throats, then collecting whatever benefits they can when hard times come along for them. It's happened. One time I was informed of it by the person's son, who laughed because he knew just how stridently "anti-welfare state" his dad was. Though I'd known him about 15 years, still he told me to my face his "family" was helping him through his hard times. We're his "family", folks.
