There is also the fact that it is potentially causing costly problems into the future.
If families are removed from their communities they are, as I stated earlier, removed from their support networks. For example, if they have had to move a significant distance, they can no longer rely on grandparents to look after the kids whilst going out to work (That's if they've been lucky enough to find employment elsewhere. After all the cost of travelling to the old place makes keeping the old job impossible).
As the grandparents get older, the families are now living too far apart for their kids to look after them in old age, thus bumping up the costs of social care for the elderly.
