The TPP negotiations took place in a secret process dominated by the giant multinational corporations, and the final agreement is waiting to be approved or rejected by Congress - probably during the "lame duck" session, because that is when members are least likely to be held accountable for their votes.
With the presidential primary spotlighting a bipartisan trade revolt, defenders of our status quo trade policies are on the defensive. Their latest claim: the Panama Papers leak shows that the U.S. free trade agreement (FTA) with Panama fixed that nation's infamous tax haven conduct. An actual review of the data, however, shows that the FTA seems to have incentivized more tax haven activity in Panama, not less.
There can be large benefits to countries from trading, and there is no doubt that the United States is enormously richer as a result of international trade. But that hardly means that everyone was benefitted by the patterns of trade over the last three decades, nor is it a reason to support the TPP.
The short answer is that after much research and thought, I have realized that I cannot support the TPP as it is currently written. In many ways, I find myself in the same position as Hillary Clinton: I was optimistic about this highly anticipated trade agreement, but was disappointed and cannot support the final result.
