Aliens (Not the extraterestrial kind lol)

Go home and stay there you say
We don't need you here
But you're wrong
Just look what happened
They all stopped working
And America buckled at the knees

They steal our jobs you claim
Take more than they give
But that's not true
Because it's all the jobs you won't do
Well, for one day they won't do them too

You put up fences
And drive them away
Yet they make up a huge part of your econemy
As seen on the day
They didnt show up for work
And America buckled at the knees
