Classic example: Aspartame. Flunked human suitability at the FDA, but the corporation was owned by Donald Rumsfeld. Yes, that Donald Rumsfeld. So Reagan "got" it approved for human consumption, and Great Profits were made. Decades later it finally gets banned from food. Good old Capitalism.
The last step the SCOTUS need to take is to ban Class Action Suits (they annoy corporations), and they've been debating advancing that the last few years.
