There is a bit of a problem with GM crops at the moment actually Bobboau....
Actually, I think people are getting mixed up between ethics and practice here. The fact is that for every ideal, there is someone ready to cash in on it, and it's not just limited to America, one of the most powerful organisations in the world right now isn't American, OPEC is likely to get more powerful before it's power dies as well.
The Earth is very very old indeed, last estimate I heard was 8 Billion years. Mankind has been active as 'Mankind' for about a million years, though most of our development took place in the last 5000 (in fact, the last 1000) years, and it encreases exponentially.
Mankind puts a big gap between theory and practice, where the 'Human variable' goes. This will always happen. We often blame American companies for policies that a devised by native Management and Governments. the companies turn a blind eye as long as they are making a profit and not being caught. This truth also applies to Britain, Germany, the Middle East, and any other country or company in the world. Just as the Slave trade was often based on tribal chiefs selling their own slaves, but this is conveniently forgotten when the word 'law suit' appears, also a lot of these countries are so intent on the short term profit, that they do not apply themselves to the long term.
I'm ot trying to justify this behaviour, I'm saying that mentioning the fact they are 'American' companies is utterly irrelevent, I'm pretty sure with a bit of Web-searching etc, I could probably find equal examples of companies and Governments from all over the world indulging in precisely the same practices.
I'm not certain that Democracy is the Goose that lays the Golden Egg anyhow, since as soon as people get into power they seem to completely forget what the worlds 'Public Servant' actually means and seem to think they have the right to tell the people what they think, rather than represent their current thoughts,which is what they are allegedly supposed to do.
At the end of the day America is the richest and most advanced country on the planet, and they, whether it is liked or not, are our hope for surviving the next 100 years. Yes, they don't do a perfect job, but even the Romans had enemies and they had one of the most tolerant Empires around.
So don't blame it on America blame it on the companies, which quite often have their headquarters in some little Tax haven in the caribbean etc, so, strictly speaking, aren't American.
