We are a country of immigrants but no need to fill this glass to overflowing. Time and situations change, we have pasted to point of optimum population density. Can’t be stopped? Do you use the “can’t” word a lot? That is the defeatist’s credo! It certainly can be slowed, some immigrants are leaving of their own volition. If we can get it under control I would stop advocating that we stop immigration. In absolute terms it probably can’t be stopped completely but if the numbers could be worked down to less than a few tens of thousands a year instead of the more than a million a year we see now I would consider it under control, I would count it as the “uncontrolled immigration is stopped”.
