Along with many others, I'm sure, I don't have the time to actively wade through the long and enthusiastic discussions that have been appearing here since this list started up, it's a quick skim through to see if something hits the eye. It sounds like you've got the right intentions, but putting your faith in a treaty initiated by business and investment interests hardly seems like the right answer. Under the pre-globalization regime, power and money cross borders but small scale economic forces do not. This gives multinational corporations a devastating advantage over everyone else.
Economic globalization is the only available route toward encircling the multinationals.
So long as economies are closed, the multinationals can go where unions and environmental law cannot reach and there is no chance of controlling their false economies of exploitation and destruction. Unfortunately MAI will only encourage multinationals to exploit resources, people, and cultures around the world. Chernobyl showed that we don't want nuclear power, full stop. Unfortunately in today's already multinationally controlled media world, forms of artistic expression that are not sure fire money makers need to be subsidised and supported. Audiences need to be educated, informed, that there is an alternative.
