Trade deals like the TPP have grown so complex because the global trade community has figured out how to solve a problem that has bedeviled philosophers and political leaders for centuries: how to craft international agreements with teeth. The WTO's dispute-settlement process, which serves as a model for the TPP, puts pressure on countries to actually keep the promises they make in trade deals. That's why everyone with an agenda — wealthy investors, drug companies, labor unions, environmental groups, and so on — is scrambling to get on the bandwagon.
But the complex, secretive, and anti-democratic way the TPP is being crafted rubs a lot of people the wrong way. The agreement will have profound and long-lasting effects on countries that sign on, yet voters in those countries won't even be allowed to see the text until negotiations are over and it's too late to make changes.
From the conclusion:
We expect the laws that govern our economic lives will be made in a transparent, representative, and accountable fashion. The TPP negotiation process is none of these — it's secretive, it's dominated by powerful insiders, and it provides little opportunity for public input.
