exactly - if they truly have a trucking shortage, the prices of all the intermediaries will have to rise, including the end shelf-price.
More short-term, Wallmart will either just discontinue that product or offer it elsewhere due to free movement of capital. We'll get just a couple brands of cereal at the supermarket, instead of 25.
Not really. OP was arguing that there are no shortages, the companies are not willing offer more. I pointed out that if we were to accept that logic then we might as well stop using the word "shortage" as every shortage is likely to clear up if you pay more.
But the truck driver's worth is determined by market too so whenever someone says there is a shortage they mean shortage at a viable price point.
