Chris, I think we agree on more than you think. I wasn't insinuating that there aren't people that will still work hard. But in most areas I have seen, there are job postings all over the place, and the people who will work hard are already working. If you can still find people willing to work in Arkansas to fill new jobs, good for you, but I will assure you it is not that way in many areas of our country, and not just in the big cities.
And I too think nuclear power is the way to go, People look at nuclear power through they eyes of 50 year old technology. We have much better ways of doing it today if we just would get over the prejudice against it. (MHarryE, this is a place where technology fits well!) And I am certainly not a fan of windmills either. Solar panels have their place, but aren't a total answer. I am of the opinion we need to ween ourselves off fossil fuels but we need to do it intelligently. I am also certain we will certainly make numerous mistakes along the way.
The extreme environmentalist I was referring to were your mention of tree huggers and spotted owl defenders.
I also think those robotic tractors will be commonplace in 50 years, like it or not. But I think a person would be a fool to invest in one for practical use today.
