Because no one wants to leave their family and entire home behind just to move to a wealthy country to live on the street as a homeless person. We will only ever attract as many immigrants as there are jobs to support them.

At least up here in northern Europe that is sadly not true. I’m not claiming immigrants come here seeking free welfare (some probably do but there’s always people like that everywhere); but there’s plenty of people being actively lied to in their own countries, and sold this idea that you can just go up north and get a job and send money to your family etc. get a better life! So they gather all the money they have and give it to these liars, who then traffic them into EU and up here.

There’s barely any jobs in my country you can get without speaking the native language (which is difficult to learn and useless outside our 5mil population), and at this moment we even have massive unemployment crisis so there’s no jobs even for the natives. Still people are sold lies and come here, then get stuck trying to scrap any money they can, and get taken advantage of and have to live in poverty. Some even have big loans on them, they took to just get here. All in vain
