Nothing you said I disagree with yet your tone suggests TPP is by assumption a good thing simply marketed wrong; yet you've not made a single argument for why it is good. It's not just the US government that did little to convincingly persuade the populace about TPP's advantages; nobody convincingly persuaded anyone about its advantages except for the tiny group of elites who negotiated and structured the deal in their own favor.
I'm willing to hear an argument for why TPP would be good for working people in the US. I've never heard anything even close to that. I've heard plenty of hard evidence that it's horrible for working people (and people in general) in the US, while being great for large corporate interests. Sometimes unpopular things are unpopular because they are bad, it's not always a communication problem.
