I'm a fan of this @binarybits.bsky.social piece that points out the incredibly simple and dumb error made by shadowstats. There's definitely some wiggle room for how you calculate inflation but you can't be significantly biased in the long term without it being obvious.
No, the real inflation rate isn’t 15 percent
Jordan Peterson and Jack Dorsey are touting a bogus theory about the inflation rate.

Groceries stores are famous for their fat profit margins.
NEW: Two-thirds of NYC voters support creating municipal grocery stores to bring down prices.

This is what Elon does: he takes something someone else is already doing, does it more sloppily/dangerously, and slaps his own brand on it so everyone forgets anything else exists (if they ever knew). You can't cede his rebranding without a fight, or you're toast. Explain that GAO already does this!

Elon Musk backing off his goal of cutting $2 trillion matters because:
- Trump’s operation is already abandoning key campaign promises
- misguided DOGE hype is unraveling
