Not so much stupid, as cynical. They create the panic, which then gives them next weks headlines with footage of empty shelves, which they will probably blame on Brexit again.
The shortage of truck drivers at the moment, may well have the same underlying story as the shortage of a lot of types of workers.
I was speaking to a Director of a large building company recently, who was moaning about a dire shortage of bricklayers.
He told me he employs eastern European bricklayers (mainly Romanians) because they are cheap to employ.
Now they are all sat at home in Romania with no intention of even considering coming back to the UK until furlough ends.
Despite being in Romania, they are being paid 80% of their UK wage by the British taxpayers, and can live like Kings there,on the money they are getting for doing nothing.
Cant blame them, but we can blame our useless spineless Govts of the last 25 years.
