The fed playing with interest rates certainly has and has had a direct and measurable impact on the current economic situation.
You can argue that the fed is independent from the president, but the fact is they generally do whatever the president suggests.
You know, there was a girl I was chatting with once. She suggests we get lunch, then calls it off last minute.
A few days later she complains about some guy she likes who stood her up for lunch that lives near me.
Then she just ghosted me.
I've always wondered if she meant me and the whole thing was her miscommunicating and then trying to be coy and indirect.
