Or maybe there just isn't enough people of working age available to make up the shortfall across nearly every sector because we told all the foreigners regardless of profession to get the fuck out of the country.
Before you start on the whole forigeners we're keeping wages low bullshit, multinational multi million pound businesses along with the Tory Government kept wages low, not foreign workers.
Also don't bother using HGV Drivers as an example of wages increasing because it will only be temporary.
Just spend a few minutes doing an ounce of research you we will find many examples throughout the decades where jobs that paid well decreased as the availability of people increased.
As more and more people train to become HGV Drivers to take advantage of the signing on bonuses and wages then the pool of available people who are able to do the job will increase.
This in turn means that businesses are able to lower wages as there is an increase in competition for those jobs.
I saw my own profession go from paying £25 - 30 p/h to £10 - 15p/h in under a decade because the amount of people who jumped profession to take advantage of the pay meant that the demand for outstripped the availability.
But hey, it was worth it to stop all those horrible forigeners coming into country.. Oh that's right, it hasn't so it was all fucking pointless.
