How much is enough?

Tell me, can the hateful chain be broken?
production and consumption define our hollow lives
avarice has led us 'cross the ocean
toward a land that's better, much more bountiful and wide
So when will mankind finally come to realize
his surfeit has become his demise?
how much is enough to kill yourself?
that quantity is known today
as we blow ourselves away
Tell me, is there anything so sure?
rapacity, tenacity, capacity for more
like a dog that feeds until he suffers
the infirmity of man is brought on by his selfish cure
