Thin air

My hungry jowls are lean and thin
I am a beast, I play to win
Ruthlessly, I seek to grow
By devouring those below

My simple goal, to win the race
On this planet and in space
I always get the fattest cut
And I should be happy but

The voice that says I shouldn't care
When I am carving up my share
Is not as strident as before
It's bugging me about the poor

At night, when I should be sleeping
I hear the sound of people weeping
The thin air fails to hold me up
Liquid is spilling from my cup
