Way back in 1990, when I was still working with Immigration there was a study/research paper produced by the Fraser Institute that showed how every dollar spent on immigration was returned to the economy 7X.

7X!

That’s a fairly decent return! Anyone arriving here is essentially a total consumer, requiring all of the normal everyday items that those living here already possess - - appliances, furniture, cars, clothing etc.
They pay taxes on these items as well, on top of the taxes they pay from income.
Of course little to no money is retrieved immediately, and this is where the disconnect in perception originates.
Try to imagine the economic outlook of this country WITHOUT immigration! Stagnant to negative growth rate as birth rates have nose-dived.
The government does a poor job of selling the upside of immigration, and I have to admit that supercharged intake numbers is not an especially brilliant solution during a time of housing deficiencies.
