Don't forget that the pedal company has 3 suppliers who have suppliers who have suppliers who have suppliers, etc. all the way to oil drilling for the petrol to create the resin.
Same idea for the tire company, the frame company, the handle bar company, the seat company, the assembly fixture company, the toilet paper company, the xerox machine company, the reflector company, the display rack company, the promotional sign company, and on and on and on.
I have thought about that. It seems to me that the only direct benefit is from an immediate supplier. Distant third step suppliers would seem to have no effect. Only the direct effect on the cost of goods portion of the balance sheet which is only affected by the immediate supplier. I don't see how the oil well would have any effect at all except on the refiner.
Also, throughtout the pipeline you will have both: unprofitable companies and companies who resist lowering prices.
