I know you've touched on this before (the knowledge based economy kind of thing) but I see the wage gap continuing to grow between rich and poor. The smart and knowledgeable will get most of the wealth. It was true before as well (except for entertainers and those born into it) but at least there were alot more manufacturing jobs for the less skilled to do and earn good wages.
Now, you're going to have the highly skilled elite creating everything and having manufacturing, sales and support offshore. So, everyone else just gets to wash cars. Kind of like Brazil with rich people in walled communities and the rest in slums.
Anyway, I'm not really arguing, as I of course, don't know what the future will look like. I'm not too good at predicting the future, though a little better at predicting my own future.
