I think the real question in all sorts of financial setups is really “is the dollar actually worth a dollar”. So when company A invests in company B which buys from company A the actual question is whether the valuation of the investment and the valuation of the purchase is correct or are they getting high on their own supply
A recession is a cash/dollar bubble.
First cash/dollars are considered bad so they collapse in price. When the psychology shifts, suddenly the dollar climbs in value and itself bubbles over, causing a recession.
