> Jobs can easily head towards the cheapest, least regulated economy, but workers are prevented both legally and economically from moving towards the places with the best working conditions.
Ah, the ideal of perfect labour mobility. Even if we did remove the legal and economic restrictions, we still can't achieve perfect labour mobility without breaking down a person's social ties to family, friends and community. Although some neoliberals have put a lot of effort into doing so.
> And when workers in these countries do manage to achieve a modest increase in working conditions and therefore wages, the employers can simply pack up shop and head to the next cheap market.
It's true, just as "Made in Japan" and "Made in Taiwan" were once considered how "Made in China" is today. And now we see the rising wages in China triggering manufacturers moving to Indonesia and the Philippines.
In this regard at least, the globalisation of manufacturing is a force for good. I presume that they'll run out of countries to move to eventually.
