continues, it is going to double by 2030. there doesn't seem to be an end in sight. what's driving the driver shortage and why should truckers be exempted from the vaccine mandate in your belief? >> an increase in consumption is driving it. the economy is outpacing the industry ability to serve it. we have to move more goods with fewer drivers and trucks. we came into this pandemic short 61,500 drivers and they restocked the shelves, milk, eggs, bread, toilet paper and the ppe and test kits and vaccines themselves. we've been serving the economy throughout the pandemic. because of the slow return to work across all sectors and the high consumption rates, we are already up to 80,000 short now. it is compounding the problem. we have to recruit more aggressively to shore it up. >> julie: chris, thank you for
