I don't question that. However, the millennial generation is NOT dumber than its predecessors, and almost certainly not more lazy.
We have always had a very cushy lifestyle in our generation.
The government education industry complex has taken advantage of that. See monstrous palace dorms and gourmet $20 a day meal plans.
And, of course, labor force participation rates have plummeted due to these types not entering the labor force.
And of course this has nothing to do with the Boomers retiring and somehow having a good lifestyle dictates the type of person you are.
