> but does not necessarily reduce the supply of goods

Every mainstream economist agrees that rising interest rates increases unemployment.

Well you need human beings to go and make stuff like food and gas. That stuff is also already made as efficiently as possible. So supply is definitely, also, going to be reduced.

I think you are right, but keep in mind we are currently in the middle of raising interest rates and unemployment has not gone up. So what I am trying to say is, rather than say A (rising interest rates) -> D (recession), acknowledge what happens is A (rising interest rates) -> B (less money supply) -> C (less employment) -> D (recession)

Because if you don't acknowledge the steps, you can't explain what is happening today. Rates are going up and unemployment isn't. The economy is complicated.
