The Wal-Mart Event Horizon

Everyone knows Wal-Mart devours its competition, but no one has yet grasped the true seriousness of the situation.
The future: Wal-Mart continues to expand and diversify, evolving from Super Wal-Marts into Ultra Wal-Marts and Uber Wal-Marts, until finally the entire surface of the Earth is converted into seven Omega-Marts, one on each continent. Everyone will work for Wal-Mart, rent apartments from Wal-Mart, spend their wages at Wal-Mart. Pretty soon the Wal-Buck will be discarded completely and everyone will just have to eat at the complimentary employee's cafeteria and their only possessions will be their Wal-Mart uniform and nametag. They will live in Wal-Hovels and eat Great Value gruel, and everyone on Earth will be a Wal-Slave.
By this point, upper management will have become incestuous and demented and will probably actually all commit mass suicide some afternoon after lunch, but no one will notice and the Wal-Slaves will labor on in ignorance for hundreds more years, because the secretaries will simply keep taking messages and refusing to forward calls.

what's fascinating about this scenario is not its uniqueness, but rather the way that I arrived upon it in a completely aesthetic sort of way, and only then did I recognize its similarity to Douglas Adams' crappy-shoes-destroy-the-world scenario and probably alot of other things I'm too lazy to recall at the moment. In other words, um....

...whatever.
