“ Employment isn't really an argument I'd invoke, however I do think that bringing in cheap labour from other countries pushes down wages.”
There’s no evidence of that. Labour from overseas actually costs more and is utilised because of need for skills and labour.
On your other points, I get it. I just don’t feel the same and I’m not bothered about what demographic make up the country has. The UK exports its people and culture plenty and always has, so if people from other countries want to come and live and work here that’s fine by me.
The people who built the country are dead, and you could go back before the Norman conquest if you want to be pure about the indigenous people of these islands, and then even back before Roman times. To me it just doesn’t matter and I have no issue with change because it’s inevitable and always has been.
I'd say the need for skills and labour is only there because of how we do things in the first place, as well as the circumstances of the immigrants making it convenient for them to be hired. It still pushes down wages in general across the board IMO.
For example, I know a hotelier on Arran who openly admits he hires Europeans because he can pay them minimum wage and have them live on site. This works well for him as he has reliable, hard working staff who don't need much time off. It also works well for the Europeans in question because they are young and see it as part of a travelling/adventure experience. Unlike many native Scots, they aren't trying to mate, set down roots or pay a mortgage at this stage. They don't mind socialising with those in the same boat in the evenings, with the rest of their life revolving round the hotel, then they can take their savings home. This works well for the hotelier and the Europeans, but not so much for the young Arran natives who want to have enough money to eventually buy a house, get married and provide for a family. They won't be able to do this on minimum wage, so they go to the mainland, never to return.
You can say that labour from abroad costs more, but if that's the case (and I don't believe it always is - training a native person on the job or putting them through qualifications costs a fair bit) then it can still have the same wage-lowering result, although this isn't always the case with every type of immigration.
As for Brits moving abroad, I'd rather that didn't happen either to be honest.
Those who built the country are indeed dead, but I'm a descendent of them and it means something to me. I suppose it just depends how far back you go. I look at photos of older generations of my family who I never met, but still feel a connection to areas they lived in, jobs they had, graveyards they are buried in and buildings they lived in. It interests me. Feeling a connection to those who built the roads, ploughed the fields, shaped our laws and worshipped in the churches, fashioned the culture etc before us is just the same thing IMO. I accept that most people don't share my mindset in this regard, but it's just the way I am I suppose.
