I understand that a surprising number of jobs in the US require some kind of licence or qualification.Supply chain issues are manufactured by the shipping lines that lost tons of money in the first year of covid and are now getting compensated by holding backs ships, with a wink from the US government because shipping lines are national security and no one wants them to go out of business.
I can also tell you for a fact that truckers are hard to come by because those failing drug tests are entered in a national database and can't be hired. Trucking companies simply can't find drivers who aren't dopped up. In fact, supply chain companies which all have stringent drug testing and firing policies simply cannot find labor because so many fail dope tests. Welcome to the land of bright and brighter.
Supply chain issues will miraculously disappear when shipping lines have recouped their losses.
I'm talking about barbers and bar-staff here, not lawyers or surgeons.
That's not exactly encouraging free employment.
