Yeah it's fair to say that if suddenly a huge influx of people show up causing downwards pressure on wages then that can happen. Though I feel like construction work is a place where there is legitimately more limits to how many people who are willing to work in that industry (even if you paid me double a SWE salary, I'm not working in scaffolding all day) locally.
I do think that if you don't tie the visa to the employer, then it's _less interesting_ for an employer to recruit people from abroad. Especially for companies whose entire business model is "get cheaper IT labor, locked into mandatory service, in exchange for being an entryway to the country".
Like if you despise those shops, then you really should be lobbying to get rid of the employer lock-in.
