I partially take issue with his conclusions.
I don't think the Boomers have sabotaged the nation any more than other groups.
Boomers invented "bottom line evaluation" and the Xers adopted it whole hog. It's a way to ignore any non-financial aspect of anything. As a result, if it doesn't pay back it's unimportant. Things like arts, humanity, history, etc.
WE, the Baby Boomers, gave the world Reagan, trickle-down economics, de-regulation, and the destruction of unions as a force for the good of the common man. WE, the Baby Boomers, turned the USA from a 'tax and spend" country with rotating deficits and debt that was the largest creditor nation on the planet into a "borrow and spend" nation with institutionalized deficits and crippling debt that is the world's greatest debtor nation. WE, the Baby Boomers, took a nation that built and maintained infrastructure that led, and was the envy of, the world to build the largest most successful middle class in history and turned it into a country that doesn't build much of anything and is allowing the things our parents and grandparents built for us to crumble around our heads while our middle class shrinks in oblivion. WE, the baby boomers, gave us Drumpf. WE, the Baby Boomers have largely been a malignant cancer on this country.
