Presumably, Somebody Intended This Outcome but Who and Why?

From The Evening Standard:
The Freight Transport Association estimates that as many as 20,000 delivery drivers have taken early retirement or moved to different jobs since the Certificate of Professional Competence became mandatory in September.
The qualification, a new European requirement, involves 35 hours of training and costs up to £300. Drivers who do not hold it risk a £1,000 fine.
James Hookham, managing director of the FTA, said: “This is the first Christmas when we have had this requirement and many drivers are saying ‘I didn’t take up truck-driving to go back to school’ and just voting with their feet.”
I don't think this is special pleading by the hauliers, the government has been piling stupid regulations on them for years, overall, their complaints are justified.
So what's the point? Who stands to gain from this? The people doing the stupid courses?
