The Biden-Harris administration said as much constantly.
When the gaslighting failed to achieve the desired effect (make everyone believe their grocery bill is half of what it actually is) - then they just changed the message to "those darn greedy mega corporations are price gouging you!".
The citizens of this country gave a large middle finger to the gaslighting and bullshittery that was the economic messaging coming from the Biden-Harris administration - and then when Harris failed to enumerate how her administration would be different than the existing one... she was doomed.
