The ones that do not benefit from this do not want it, but there are family businesses that would fail without the cheap workers from other countries, I am not making the point that cheap work is a good thing or a bad thing, just that people are benefiting from this. Also this workers are working hard jobs in agriculture or constructions, with bad conditions, the citizens would not accept to work this job, for the agriculture obs I am not sure if even with bigger pay the regular citizens would want to work hard physical jobs outside in the bad weather.
