I will put it plainly for you. If the Biden administration and/or government economic agencies were cooking the books, why did third quarter GDP growth get revised upward after the election?
The message you send out is that the economy is terrible and the government is making up the numbers to hide this fact. If that is not what you think, you should reconsider the message you are sending.
I get that the economy is not perfect and there are some issues that should be dealt with. Inflation adjusted personal income growth has not been great when compared with 2019. It's maybe marginally higher, but that's nothing to trumpet over a 5-6 year period. The labor market is most likely cooling off, which I contend is not really a problem given current unemployment levels. Auto loan defaults are rising a bit.
However, the economy is not terrible. I don't think it's as good as it was in 2019, but it's not terrible. And I wouldn't listen to people like EJ Antoni or anyone else that puts Ph.D. in their Twitter byline or insists on being called Dr. in public.
Moreover, I highly, highly doubt the BLS and BEA are cooking the books. They're not perfect and there are things they can improve upon. For example, the birth/death model the BLS uses could use a lot of work. Insisting on them making things up or falsely adjusting numbers makes you look like a crazy person.
