We are all connected

This is why the "conservative" attitude of "you're on your own" is so pernicious:

Each of us must come to care about everyone else's children. We must recognize that the welfare of our children is intimately linked to the welfare of all other people's children. After all, when one of our children needs life-saving surgery, someone else's child will perform it. If one of our children is harmed by violence, someone else's child will be responsible for the violent act. The good life for our own children can be secured only if a good life is also secured for all other people's children.
