While picking on dumb articles in one's local free alt-weekly is a bit pointless, I just can't resist doing so with Georgia Straight's Debunking the Paradise Myth. I think I'd sum it up as: 'I used to like Thailand before all these damn tourists showed up. Also, you should all stop going there, it'll really improve the place.'
Tourism is not a panacea, but expecting a desperately poor nation with the natural beauty of Thailand to reject tourists (and their money) in order to help the poor is not in line with reality. By all means, ethical tourism should be encouraged and sex tourism discouraged, but calling for people to stop going to countries impacted by tourism is as naive as going to Thailand and being surprised that it has bugs, snakes, pickpockets and scam artists.
