This comic is staggeringly misleading. Here's a shotgun blast of problems with it:
* China is not a party to the TPP; China's absence from the treaty is practically its defining attribute. Yet the comic allocates large amounts of space to China's relationship with the US and the US trade deficit, neither of which are targets of the TPP.
* The comic is many, many pages long and only begins talking about the TPP at the very end. In that discussion of the TPP, there appear to be a total of just two panels actually based on any text from the TPP, despite extraordinary claims made about the breadth of the TPP earlier.
* It has an extended segment on US job exports, as if the TPP somehow changes the fact that every job that could be viably exported to Asia already has been. The US does not need the TPP to outsource manufacturing to Asia.
* The most important goals the US appears to have in the TPP is to harmonize intellectual property rules across the Pacific Rim. There is a very reasonable, very important argument against making Asian IP law more like the US, which is that medical care across Asia depends on lax IP laws. What does this comic have to say about intellectual property? They're coming for our music downloads!!!
* It has an extended segment about an evil robot that alternately represents either the finance industry or (once again) China and never connects it to the TPP or, for that matter, reality --- it's a pure appeal to emotion. "Modern finance is scary; reject the TPP!" The segment isn't even internally consistent! This is the lead-off argument the comic poses against TPP, and it boils down to "finance is friendly right now but might not be in the future; China".
* Despite the domain name, no economist seems to have had a hand in its authorship. The author himself is not an economist.
Like I said last time this came up: if you're looking for coherent opposition to the TPP, there are great economists you can read to get that information. I'd start with Dean Baker at CEPR. Please: oppose the TPP for real reasons, not because some bullshit comic told you to.
