These ages really should be legally aligned. If you're not responsible enough to live your own life, you've no business telling someone else how to live.
When I was in my teens and 20s, I felt like older people were just rigging the rules for their benefit. As I approach 40, let me tell you younger folks something (even if it's useless), we are all on the same team and we're trying to make things the best we can (for you too). And when you get to this age, you'll do the same and younger people will rail at you the same way.
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.
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.
A big club in Tokyo was the only place I was ever asked, and even there I was waved right through. Apparently, they were just checking for "gang affiliation".
