The countries that will do worst are those where the population is aging the fastest, and those where their governments have given the most generous promises. Again, we are looking mainly at Europe to find this combination of problems. But even in Australia, the conflict could become a problem and lead to all sorts of behavioural changes.
At the very least, we should question the assumption that age and poverty are positively related and that concessions to alleviate the latter should be directed at the former.
