Another dodge!
I don’t know of any country in the world that doesn’t control immigration by some means or other.
There’s a ton of reasons for that…some bad (maybe most), some good.
In this world US and Western Europe has taken an unfair share of resources for hundreds of years (you’re self evidently right about tha)…no one can do anything about that.
So in this real world what immigration policy do you want your Democratic government to pursue?
(Would it be any different to one pursued by UK Conservative government? Basically to try to limit immigration to people with useful skill sets such as doctors, nurses, lorry drivers via a points system…flexing numbers as needs change.)
