The ports got backed up because we turned off the economy and then turned it back on full blast without thinking about how much inventory had been burned down and how much would be needed to replenish. When companies can't get what they need quick enough they start ordering more ahead of time so they don't run out. Then shipping picks up and we get situations where we have so much inventory that needs to get pushed inland but they don't have enough port workers, truck drivers, railroad capacity etc. I see it every day in the company I work for. We are getting orders through the roof, but we can't get parts so our backlog grows and grows. You can't turn off the entire world's economy and then turn it back on without issues. Never should have shut down in the first place, but politics.
