... didn't that quoted bit, like. Answer the question posed in response to it?
E: Actually, now it feels like that was an amazing example of exactly what the quoted bit said. If that was intentional, bravo.
It's kinda difficult to articulate an anti-globalist POV without coming off at least partially nationalist (unless you delve into pure Marxist critiques of "exploitation of the global worker class by the wealthy"). Wasn't meant to be nationalist so much as pragmatist.
I mean, seriously...what is a country supposed to do if a quarter of their citizens are unemployed because the jobs that that quarter would normally fill have been offshored? And the loss of income tax revenues makes it doubly harder to support a social welfare system to keep those unemployed in a decent standard of living? It's unsustainable without some new sector of the economy arising (the way that the boom of IT and biotech helped soften the blow of losing basic manufacturing for the US). If somebody invents cheap energy and viable space travel, then hey sure...the rest of the world can build stuff and keep it running, and we'll all go colonize space. But until then, we have a problem.
In my mind, "nationalist" critiques of globalism seek to assign blame to the workers. Rhetoric about stolen jobs, "unfair" competition, etc. I have no problem with the guys in Chennai or Bangalore who are filling the IT jobs that used to be here. It's not their fault. They're good people who just want a good standard of living for themselves and their families, and they're typically hard workers. But their ability to work for $6/hr is directly harming my ability to make a decent salary. Or even keep my job. I don't see rational self-concern in this instance as selfish, racist or nationalist.
Rightist rhetoric on this pits workers against workers (and sometimes governments), while leftist rhetoric pits workers against employers (and sometimes governments). It's that "sometimes governments" where you see the weird marriage of the two, as in opposing free trade deals or regulatory things like opposing H1B visas.
