Wow. While a case can be made that the anti-globalization movement would of had that effect, that was not its goal. I really should stop reading the Economist.
This is just one more aspect of the general rule that these protests do not have a unified agenda, because they're composed of diverse individuals with diverse goals. And in my ignorant opinion, a lot of those diverse individuals demonstrably have no clue what they're talking about, except of course in the domain of their personal misery and frustration. I recall, then as now, lots of anti-WTO (and anti-APEC 2 years earlier) protesters who had some pretty blurry ideas about what they were fighting for. There was lots of thinly-veiled "trade will steal our jobs" rhetoric in there - of course along with the environmental concerns, the third-world human rights concerns (Suharto was a big issue in the APEC '97 protests), the concerns about capital flight and race-to-the-bottom, etc.
