The kerfuffle over TPP has me once again considering what we know about "Free Trade", or, just, trade. Anybody who took Econ 1A has seen the "proof" that trade benefits both countries. But, the "proof" doesn't say anything about who in those countries benefits. My hypothesis is this: trade between a rich country and a poor country generally benefits lower income workers in the poor country and hurts lower income people in the rich country. I don't have any proof of my hypothesis, other than that is generally what has happened in the U.S. in recent decades. But, the software revolution also happened, and, that also has hurt a lot of lower income people. My worry about TPP is that it is going to tie the hands of policymakers who want to boost employment and wages for lower-skilled jobs. That is a big deal to me. Lower income wages have been sliding for decades, and, even so, there is still a shortage of lower-skilled jobs.
