I visited Russia in the early 90's to find vodka distillers for a drinks manufacture that no longer exists. This Russian brewery employed this one old guy whose only task was to knock on the barrels as they rolled into storage. I asked why does that guy tap the barrels? I was told that if he didn't do it he wouldn't have a job here. It served no purpose but to give him a job.
It what the US government has been doing for years.
