So in a step by step process. Let's just use generic examples. Wal-Mart chooses Politician A. Politican A has vastly more financial support from Wal-Mart and thus is able to create ads, marketing and media coverage at a far larger rate and ability than Politician B, who didn't want to play ball. American's are stupid and fickle, so they hear a bunch of good shit about Politician A and his name is ingrained in our psyches, so we vote for Politican A for President. Repeat this process for all congressmen and senate in local arenas. President A now appoints supreme court judges who are also paid off by the Corporations, so now with the support of Congress, The President, and the Supreme Court, Wal-Mart starts to implement legislative changes to the country.
Unions become illegalized, Monopolies are now ok so Wal-Mart can buy out all the competition, Wal-Mart gets permanent tax breaks to where they and other corporations no longer have to pay taxes at all, they fix this deficit by increasing the common mans taxes tenfold. Minimum Wage gets dropped down to less than $3.00 an hour to minimize financial output for workers. Full Time work no longer requires the addition of benefits, and is now increased to 80 hours a week instead of 40. Pensions are no longer necessary, and the retirement age or eligibility for social security gets raised to where you have to be 85 before you can collect. And if you can't work for Wal-Mart under these conditions? You can't feed your family and get left behind.
What are the common people gonna do? Revolution? When the Corporations have all the guns, bullets, and support of the US Military, how far do the people go before they're all slaughtered?
Hence the question, death of US Democracy as we know it? Or is Keith Olbermann and the rest of the Liberal Media freaking out over potentially nothing?
