In the coming global food riots, keep a close eye on women who don't go barefoot: when things get grim enough that families start eating the youngest children, it's the mother who wears shoes who will eat her babies in secret so she don't have to share.
Deuteronomy 28: 56-57:
56 The tender and delicate woman among you, which would not adventure to set the sole of her foot upon the ground for delicateness and tenderness, her eye shall be evil toward the husband of her bosom, and toward her son, and toward her daughter,
57 and toward her young one that cometh out from between her feet, and toward her children which she shall bear: for she shall eat them for want of all things secretly in the siege and straitness, wherewith thine enemy shall distress thee in thy gates.
On the other hand, a woman who wears Vibram 5 Fingers will still eat her babies, but she'll at least offer her husband some of the lesser cuts of meat.
UPDATE: People a lot smarter than I am have pointed out that the warning is even more dire than I thought. It turns out *everyone* is going to be eating babies, not just shoe wearing moms.
