We've finally hit the point where the UK government is simultaneously complaining we are "full up" as an anti-immigrant message, and simultaneously saying we need to increase the birth rate.
Guess what - immigration is *far* better economically than babies. Babies take 16 years to develop taxable skills, and are heavily state-subsidised for those 16 years. Immigrants, on average, already have taxable skills.
Culturally, I see immigration as a plus too. Others don't. You judge that one.
