Is this a real thing? I follow Stoller on Twitter, and have never heard him say anything like that. Just that predatory pricing is often snuck in under the guise of "discounting" (which is true).

He's definitely a centrist on economic policy, which turns a lot of people away (most Americans have never heard of a centrist view of any policy of any kind, and most Americans are far more conservative than they'd ever actually admit to). But nothing about him seems ideologue-ish, and he's certainly not anywhere near left-wing on economic policy.
