David Brooks and Gail Collins on the future of the American Dream. I find myself agreeing with both of them. But without an economy that heavily leverages advances in science and technology, it’ll be very difficult for me to be at all optimistic about the future. So we not only need a creative class (think Richard Florida), we also need that creative class to be producing real products that offer solutions to our huge problems (think the intersection of climate and energy or health care).
