OK, then you don't believe in basic economics. I guess the reason that basically 100% of companies lobby for increased immigration is just out of the goodness of their hearts.
I didn't say the problem doesn't exist, I don't think it's the main target though. You also said "illegal" immigration, implying that by kidnapping millions of people, we'll solve the affordability crisis in the country.
Businesses love illegal immigration not only because wages are /somewhat/ lower but because they can abuse workers and steal wages.
