What the Prussians did was find an excuse to get the older, less capable people off the assembly line.
And we could afford retirement because of the extra production capabilities of the assembly line.

Rare is the boomer who has any sage advice to give.
The times, and technology has completely changed
Their programming/indoctrination is actually detrimental today (go to school, get a job, get married... These are all things that have lost all their value, and come with a high price tag)
What can the free love generation teach about being a loving partner? (they already taught us about divorce)

So, if we had a "tribe", what would we do with these boomers?
We don't even like the way they raised children.

It would take a lot for us to accept them into the "tribe".

I hear every once in a while, in the news, about euthanasia assistance becoming a thing.

On retiring, i suggest everyone forget that word.
Instead, work on refining your life.
Become financially independent.
This can be as little as having your own house and stored food to last 30 years. (basically no expenses)

But, you do not work to stop working, you work to find what you really love to do, and making that a reality. If you have enough money to pay the bills, you can do whatever you find makes you happy.

Unless sitting in front of the TV drinking beers is your happy place, then there is so much you can do.
