NGl it's big business that's been pushing hardest for the mass importation of immigrants. Immigrant labor can be paid less, has fewer rights, is more prone to suffer wage theft and it allows the copros to offload native born, higher paid employees. Same thing is in the US WRT the agriculture. I have friends that have degrees in horticulture and actively tried to get jobs on farms but wouldn't get hired.

White, native-born Americans don'tcha know. They come with legal protections and income minimums and we can't have that!

Countries really need to put the boot to big businesses that demand mass importation of cheap labor.
