Rounding up the chosen ones with censuses and punch cards
Efficiency of the utmost importance, every last one must be found
Nameless and numbered, gassed, tortured, murdered
En masse and quickly with some help from overseas

Some are in for profits, some to cleanse their nation
For the ones deemed unpure - extermination

No one escapes, when they're sorted out they board the train
that will lead them to the camp where work will set them free

Dealing with both sides, THINK only about numbers
It's easy to ignore deaths across the pond.
