Human society!

Why does it happen so,
the dark seed that the rich sow
is often seen reaped in a poor mans field?
You hold the gun,
they take the bullets.
Tearing them apart,
from head to toe.
Why does it happen so?
Is this how the rich remain rich?
And the poor become poorer,
Cause they know not to deceive,
they are innocent folks.
They have no gold to offer,
no diamonds, but coal.
Yet you strip them,
make them sell their souls.
Why so cunning?
Why so cold?
Why does it happen so?
