"Your spending is my income, my spending is your income"I'm not quite following you.
A weakening economy means demand is dropping. The drop in demand means there is excess supply/production capacity. Companies cut back to reduce the excess supply and misallocated production capacity. Some of this is weaker companies going out of business. When the shakeout is over, the economy can improve and you go back to a growth cycle. Typically, this is an 18-24 month process. The Depression of 1920 (which is referred to in The Great Gatsby) lasted from Jan 1920-July 1921. The Panic of 1893 was one of the worst before the Great Depression. It lasted 4 years.
It's painful but there's no way to avoid it. The goal should be to not make it worse. In trying to avoid the pain, Hoover turned a 2-year problem into a 12-year problem. There was a big concern that the US would go back into Depression when WW2 ended. Things picked up when the Revenue Act of 1945 repealed a chunk of the wartime and depression taxes.
If car factory cuts production, then the steel company would experience a further drop in demand. They would also start lowering prices and have to lay off workers, which would then impact other firms upstream. Which eventually mean there are less people who are capable of buying cars due to layoffs: and the whole cycle begins again.
So everyone is worse off
