What the longshoremen need to realize is that EVERY node in the chain of logistics is critical. The longshoreman boss seems to think his crew is the ONLY one that matters. But there are truck drivers, ship pilots, barge pilots, railway engineers, warehouse workers and a whole slew of other people whose participation is also critical for the supply chain to function. If any one of these fails, the entire system craters. The striking of longshoremen will only accelerate their replacement with automation systems that don't go on strike and don't threaten to deliberately break supply chains.
