I think one of the bits that’s often missed in this narrative is that importing skilled workers is cheaper than investing in training and that causes a secondary pressure. Skilled immigrants aren’t directly competing with unskilled domestic labourers because the domestic workers lack the necessary skills for the jobs. But they often lack the skills because governments and companies have no incentive to fund training to ensure that people have those skills.
When there’s a short-term shortage of a particular set of skills, importing people with that skillset is the only solution. When there’s a long-term shortage, you need to invest in education and training. Immigration is a very fragile solution because as soon as your country does something stupid (such as Brexit, or electing Trump), the supply of foreign skilled workers who want to live in your country contracts and you now have an even worse skills shortage because the lack of training and the large supply of workers has put off people from taking advantage of whatever training might have been available.
A lot of the NHS has been largely supported by importing talented people while simultaneously gutting funding for medical qualifications, for example. This is not sustainable, but the ease of turning on the tap of skilled immigrants over the last few decades has allowed successive government to pretend that this wasn’t a problem.
Immigrants on visas that are tied to their employment are also much easier to exploit than native workers who can change jobs more easily, which depresses wages for everyone.
I am still of the opinion that work visa sponsorship should be moved from companies to unions and professional bodies. If there is a skills shortage in a field, constricting the supply of immigrants would give these bodies leverage to get funding for additional training, apprenticeships, and so on. And if companies needed union approval to be able to hire immigrants then you’d eliminate the ‘working conditions are so bad that no one with options would accept them’ problem.
