Professor Richardson, who is working from a The New York Times article, to which I have no access:
Supply chain issues have also driven up prices, both because of shortages and because the ten shipping companies that dominate the global trade have jacked up prices so astronomically that U.S. importers have asked the U.S. government to intervene (this year container companies will pocket $300 billion in profits, up from $23 billion before the pandemic).
Well, that explains a helluva lot. Way too much, in fact. Profits, that is.
