Via Musings from a Stonehead, I learn that the UK has new standards for poultry, bigger and better cages if I understand. This is, I think, the wave of the future. The richer we get, the more we pamper our children, our animals, our environment. (I realize "pamper" reveals my age.)
See Megan McArdle's piece on spanking, the decline thereof. She argues that modern parenting is much more intensive, which to me reflects the greater availability of time and energy for child-rearing, due in part to having fewer children per household.
