It was out before, the McCain camp is just running out of negative stuff to say about Obama and they have to pick every little minute thing they can find and magnify it.
Guess what? Coal=carbon dioxide=greenhouse effect. If you hadn't realized it yet, a big part of Obama's program is to lessen carbon dioxide emissions and create jobs in alternative fuel branches. That means coal and oil companies will take hits. That is good, because those people can (with their knowledge) be transferred to these new businesses and bring new ideas into the mixture.
From a (US) domestic standpoint, McCains plans are more likely to result in reduction of jobs due to tax and cost benefits in outsourcing. Obviously, the free global market system would be the best for everyone (discounting negative externalities in poorer countries that get to produce these goods, such as higher emissions and pollution). I think the US market, looking at how many jobs are in manufacturing, is too badly equipped to handle those sorts of job losses. That's where Obama's education plans would come in handy in the future as your workforce becomes more adapted to a 21st century service sector market. Agreed?
