It has a reasonable argument at its core: giving government benefits to low-income workers effectively means subsidizing the companies that pay low wages (and there are huge companies profiting from this). That's an irony, because even the voters who want to give money to low-income people usually don't want to support companies that profit by paying low wages. Giving money to low-income people regardless of their employment (via basic income or otherwise) would have a similar result, except for requiring people to work for companies that profit by paying low wages.

It has a mindkilling title: "evil" is a loaded word, and even if we insist on using it, why not use it instead on politicians and voters who enable this behavior? The problem is, each tribe has their preferences about who should be called evil, therefore the usage of the word necessarily follows the party line.

The mindkilling effect of politics is not just that it's difficult to write a reasonable article about politics... but that even if you succeed to write a moderately reasonable article on a political topic, it is still very likely to cause unreasonable comments in the discussion. -- This is why we need more strict criteria for political articles. As it is, it is in my opinion barely okay for the Discussion, and unfit for Main. I upvoted it in the Discussion, because I appreciate the information (I am not American, so I learned something new about Walmart, which may help me understand the American culture better), but would downvote it if it moved to Main.

Yes, politics, boo hiss. In my defense, the topic of this post cuts across usual tribal affiliations (I write it as a liberal criticizing other liberals), and has a couple strong tie-ins with main LessWrong topics

This reminds me of an advice for authors: don't tell me, show me. Specifically: write an article in a way that does not scream your tribal affiliations, and then you will not have to excuse yourself.
