No, they're not wiser at all, and they haven't been through any hard times. You're thinking of their parents who went to war in WWII. Those people are mostly dead now. The Boomers are their spoiled, greedy children, who are mostly to blame for the state of this nation now.
It's also hard to keep the lower class employed with a living wage if low-cost migrants keep underbidding them for employment.
While the Boomers haven't always made great decisions, this us-vs-them thinking neglects that the Boomers generally care about their descendants. Boomers do not wish to see their grandchildren suffering.
Then maybe the Boomers should vote for higher taxes and better social services. That's what advanced nations do, after all, and they don't have these problems.
This isn't true at all, at least in America. The Boomers are absolutely pushing for policies that will benefit them at the expense of younger generations. The refusal to reduce carbon emissions and their desire to increase coal mining and usage is a big example of this.
