When the standard 4 color political compass was devised, it was intended to separate the economic and social political axes, because you can be socially liberal and fiscally “conservative” (meaning fiscally liberal), or socially conservative and fiscally illiberal (this is where most Americans currently are).
But almost everyone who uses it conflates the two axes. Almost all political compass memes identify the bottom right with reactionary social views, and the bottom left with social liberalism (such as support for BLM or trans rights), which are exclusively y-axis issues on that chart.
I think part of this is that few people, on any part of the spectrum, have any basis for their economic positions at all, so they just choose the side they think their team aligns with. Another part is that unsavory far-right groups (usually with illiberal fiscal ideas), often identify as “libertarian,” even though their ideology is starkly authoritarian, and entirely indistinguishable from Trumpism.
No amount of UBI would change voters’ opinion on single payer healthcare, minimum wage, “free” college, housing subsidies, a jobs guarantee, protectionism, and so forth.
All that matters is that you convince voters that you want to solve problems related to poverty (and whatever else you’re discussing). For the most part, Americans who advocate for “free markets” are just signaling that they don’t care. People who vote Republican broadly do so because they are more concentrated about not helping POC and other undesirables than they are with helping each other.
If you talk about issues, you never have to talk about policy.
But the political compass is about policy. There needs to be a place for people who aren’t socially and fiscally left, or socially and fiscally right, or people will never be able to associate free markets with good outcomes or problem solving.
If people are just going to identify with their tribe, there needs to be a tribe on the right side of things for people to be part of, and right now there isn’t.
