I do think the Boomer generation deserves a lot of criticism, but not because you bought a house cheaply and later sold it for a substantial profit. Of course you took the deal available to you.
The criticism is that your generation inherited one of the most favorable economic environments in American history: tremendous growth, affordable housing and education, strong pensions, manageable federal debt, and relatively little exposure to major-power war.
Then, once your generation became the dominant political and voting bloc, you repeatedly chose benefits today and bills tomorrow. You protected generous retirement and entitlement promises for yourselves, tolerated enormous deficits and monetary policies that inflated asset values, and left younger generations with much higher housing, education, and healthcare costs—and nearly $40 trillion in federal debt.
So yes, I’ll make the argument that the Boomers were the worst generation. And the irony is hard to miss: your parents were called the Greatest Generation because of what they sacrificed and built. Your generation inherited much of that prosperity and, too often, chose to consume it rather than preserve it for the people who came next.
