I'm unable to access this article — the page itself returns a JavaScript/cookie-check wall (Cloudflare-style block) rather than actual content, WebFetch was refused with a 403 Forbidden, and WebSearch permission wasn't granted so I can't look up the content another way.

Based on the title alone ("Sewer Socialism, but Worse") and National Review's typical editorial stance, this appears to be an opinion piece likely comparing a contemporary left-wing political figure or policy (the term "sewer socialism" historically refers to early-20th-century pragmatic municipal socialism in cities like Milwaukee) unfavourably to that older, more modest tradition — but I don't have reliable access to the actual text and don't want to guess at specifics, names, or arguments.

If you can paste the article text directly, or grant WebSearch permission so I can try fetching it another way, I can produce the summary you're after.
