If the government does not collect price data, there are no inflation numbers to compute. So inflation "disappears."
A much more skeptical person than myself might think this is to deliberately hide the effects of some random thing like, IDK, tariffs on consumer prices -- to use a completely made up example for purely speculative purposes.
I actually suspect this is a "happy accident" from Trump's POV: DOGE layoffs and other disruption means BLS can't collect enough data. https://www.cnn.com/2025/06/05/economy/cpi-data-bls-reductio...
