Our race has come a long
way. Where once we were a society of hunter-gatherers, we have become an
agriculture-based society. That gave way to an industrial society, where
machines began to do bigger jobs than men ever could. Where we once had a
barter-based economy, where my goats were payment enough for your flour, we now
have a monetary-based economy - you won't get anything without cold, hard cash.
