Demographic challenges (and chances?)

In the near future, we will all (except some in Asia and most in Africa) experience a drastic change in our lives and our overall comfort. What we consider normal today or may even take for granted could become a luxury or be gone completely (such as easily available food and services, travelling, free time).

Most Western countries and many on other continents already have shrinking populations. This will lead to a lack of manpower, a lack of standard of living and an overall lack of comfort. With older people who currently still work retired and not enough young people taking over, those of us who still DO work might have to work 6-7 days per week. And not 8 hours, but maybe 12-14 like in South Korea. The worst thing is that this will only soften the blow. Our overall life will still be worse, with less comfort.

So what can or should we do? Animal species that survived for centuries did so by adaptation and migration. Thus, we would have to be willing to take a lot of risk or sacrifice comfort TODAY for an overall better comfort level TOMORROW. Will we be willing to do that? Will there be some advantages to this? Maybe we will become more social at least, as incomes fall and we will have less, but we have each other?
