British spoken-word poet Hollie McNish has shouted out in verse in support of immigration. Her poem, from which I include some lines below, is entitled "Mathematics" and a video of McNish performing the poem is available here at the poet's webpage. Thanks, Hollie McNish, for making important noise on this important issue.
from Mathematics by Hollie McNish
. . .
I am sick of crappy mathematics
Cos I love a bit of sums
I spent three years into economics
And I geek out over calculus
And when I meet these paper claims
That one of every new that came
Takes away one's daily wage
I desperately want to scream
"Your maths is stuck in primary"
. . .
Cos sometime one which comes makes two
And sometimes one can add three more
and sometimes two times two is much much more
And most times immigrants bring more
