CMV: The current HGV driver crisis in the UK is what Brexit voters wanted

Logic:
1. (Some) Brexit voters felt that cheaper European immigration led to foreign workers coming to the UK to take on jobs that lowered their wages or put them out of that business.
2. With fewer European workers, businesses have now had to increase wages for HGV drivers and go on rapid recruitment drives.
3. This has lead to more native Brits getting (back) into the HGV job with higher wages.

Regardless of knock-on effects (e.g. prices passed onto customers, fuel crisis while HGV capacity doesn't meet demand etc.) this process leads to a perceived 'benefit' of Brexit.

I am not a Brexiteer, but I do see this crisis as being a short-term problem that will lead to a genuine result that Brexit voters hoped for, i.e. to higher paid HGV drivers with a greater proportion of British citizens in that job role.

Caveats: Brexit voters are of course not a homogeneous block, I'm talking about those who hold the above views. Also, whether or not this is a 'good thing' is not part of my view, just that it is consistent with a common Brexit perceived benefit.

One way to think about whether this is 'what they wanted' is to imagine a situation where the Brexit voters really believed this situation would manifest, and whether they would willingly then vote for it. 

Before the referendum any discussion of food or fuel or labour shortages, or in fact of any inconvenience whatsoever caused by Brexit, was met with the rebuttal "project fear" by most of those intent on voting in favour of Brexit.

The reality now is that - as you say - those shortages have factually occurred. And the resolution is either (1) more foreign labour or (2) increased cost to consumers to pay for the increased price of labour and logistics.

I suspect (1) will be what happens, when all the bluster dies down. But let's imagine (2) is what happens instead. Imagine the Brexit voters REALLY believed supermarket shelves would be empty, petrol stations would be shutting down and costs would increase, permanently! for the average person to pay for this situation to be addressed. Would they have so willingly voted for that?

I suspect not.
