A simple thought experiment showing why recessions are an unnecessary bug in our economic system

On Monday we all go to the offices and factories we work at and produce goods and services. We exchange these goods and services among each other for mutual benefit.

On Tuesday it’s declared there is a recession. The same offices, desks, factories, machines are still sitting in the same buildings, but now for some reason we stop going to work, and we stop exchanging goods and services.

Why is that? We could decide to just go to work anyway and do the exact same thing we did on Monday—the desks and machines are still there exactly the same as yesterday for us to use, and we can still exchange goods and services at will.
