So the real question to ask is, do British plumbers expect a too high quality of life?
Of the three who came out to quote, we went with the Polish one because he was the most professional in his manner, gave us a written quote on paperwork with a company VAT (tax) number, and gave us confidence that he would do a quality job using quality parts.
This he did, for the amount he quoted.
As for cost? His quote was the most expensive.
Try harder when trolling.
The "immigrants depress wages" trope is never that simple, as the UK is about to find out. In an economy where unemployment is very low, like the UK, they need that supply of labour to keep business ticking over. Should it disappear, growth will become constrained, and prices (along with wages) will have to rise.
Now, the question of immigration is not just about economics. It's a political question, so other factors come into play. But as far as the economic part is concerned, there is no question that substantial immigration depresses wages in specific labour markets.
The economy isn't a zero-sum game, and of all the countries in the world it would be most hypocritical for the UK to criticise globalism...
That point aside, EU /is/ a peace project and will continue to serve that purpose as long as it is standing. I do not dare think too much of how fractured western Europe would be at this point in time if we had to rely on Russia and USA for our peace.
EDIT: switched ""rely"" to "rely". Not sure why I quoted it in the first place.
Blaming based on hypotheticals is fun, even even more so when the hypotheticals sound plausible. Let's do more of it!
And then maybe realize that it's all the same plus a bunch of downsides, but now the cheap Eastern Europeans cannot be blamed anymore.
