Professor, no-one here has denied the link between immigration and suppression of wage rates. However, those of us with experience in the field, and the ability to actually think for ourselves rather than just googling other people's ideas to copy-and-paste, understand that it is not immigration per se that suppresses wage-rates, but the behaviour of unscrupulous employers who take advantage of immigrants.

Your solution to the problem of suppressed wage-rates, rather than acting against the offenders, i.e. unscrupulous employers, appears to be to restrict immigration. That is called 'victim-blaming', and is precisely the same despicable thing as telling the rape-victim that she 'asked for it' because she wore a short skirt.
