First of all, we are online since 2003 with years of experience!
And this list is far away of being complete!
This is very bad news for a planet experiencing rapid demographic aging, the scariest and most self-destructive expression being the tendency of the old to want to "keep out" the foreign or "scary" young. This is a great deal of the emotion behind America's current passion for such slogans as "make our country great again!" It is simply nostalgia for the way things were.

Young people are often footloose. With the whole world to explore and nothing to tie them down, they move around more often than their elders. This makes them more productive, especially if they migrate from a poor country to a rich one. By one estimate, global GDP would double if people could move about freely. That is politically impossible—indeed, the mood in rich countries is turning against immigration. But it is striking that so many governments discourage not only cross-border migration but also the domestic sort … A UN study found that 80% of countries had policies to reduce rural-urban migration, although much of human progress has come from people putting down their hoes and finding better jobs in the big smoke.
Filling the Gap Between War and Peace: Creating a Stability Command
No, I don't pretend this unequal burden is new, as the hunter-v-nester dichotomy is as old as humanity is. I'm just saying it's getting more concentrated or further skewed thanks to modernization and everything that comes with it: birth control, divorce, single-mother households, more educational and career opportunities for women, etc. We can pretend that the sandwich-generation dynamic affects men and women equally, but it doesn't – not even close.
Some Reflections On The Arguments
I don't make this argument casually. I've been studying the demographics of aging for years now, and, coincidentally, after my wife and I had three kids (one daughter, two sons), we adopted three girls. In effect, we bet on girls at a tipping point in human history when they're still relatively devalued in transitioning societies (our girls hail from Asia and Africa); we went "long" on girls when the world continues to "short" them.
