As a software developer who works in Europe, a large proportion of my colleagues come from developing countries and they have a great work ethic, so it doesn't seem that far-fetched that the added competition would have a significant negative impact on wages in my industry across Europe.

I agree that it's very complex though and we can't really measure how much Bill Gates' philanthropy may have contributed towards this trend.

I just wanted to point out that good things tend to have negative unintended side effects. For every deal, there is always a winner and a loser.
