Would love to see the 40 year update...
Shelling out our industrial/manufacturing economy for a "services economy" + big government/welfare economy has ended the middle class; meanwhile the political class (and media) have consolidated into a front group for an increasingly hidden ruling class/aristocracy, who like the companies behind shell companies are pretty hard to identify and lampoon.
This of course would be an intriguing book to read should someone dare to write it.
