Well people can think of something like TNG but the (alt-)right will instantly crapstorm you for being a communist. Just look at how they're opposing healthcare for all, a society like TNG would be the ultimate enemy for them.
I remember years ago having a discussion with a friend about "what's the worst ideology you can possibly imagine" and it kind of resembles what I came up with but (mostly) minus the theocracy (I pictured a pomo professor, a Christian Reconstructionist, and a fascist hashing out a synthesis). In some respects it's worse-- its obnoxious meme aesthetic is far trashier than anything I would have ever imagined. No dystopian writer could have come up with a fever dream as hideous as the collision of 4chan and Stormfront.
Maybe you have to hit bottom before things can bounce back. I have a tough time imagining anything worse than this, but I'm sure people will try.

Effectively, the governments at the time (USA), figured it was cheaper to ghettoize poor, sick, and others whom cannot support themselves. Wall them off, and keep them out of society. Out of sight, out of mind.
This literally is the thoughts of the Right-Wing. Ive seen that justification here, on HN. Why bother with the poor? They have no money! Better to keep them 'away', as 'We' are better. Of course, right now we have White-Nationalists beating on their drums. But the real war here is against the poor. Black people are.. disdained by the Conservative elite because they are primarily low income (by way of discrimination, but thats aside the point!). Ideally, all poor trash should be taken out, white, black, asian, native - you name it. No money = no livelihood = no choice = no living.
EDIT: Seriously? -1's? Am I wrong? I would love to see the conservative plans to boost people from poverty, medical maladies, and systemic discrimination. So far, what I see are attacks on any programs trying to assist with poverty, medical, and discrimination. And these attacks are done by the "ruling party", Republicans, with their base plans being as such.
This article is a great internal view of how Republicans support white supremacy values. https://www.thenation.com/article/exclusive-lee-atwaters-inf...
Not to be pedantic, but those are _illiberal_ ideas. You're conflating liberals and the left, which was mostly fine when they were in a coalition for a while. But if you're talking about identity politics et al, you're very specifically describing things that are almost definitionally illiberal.
