Kurt Vonnegut wrote in 2007 that the Great Depression "was so bad, white people had to raise their own kids."
And it got me thinking: looking at the history of European and North American middle and upper class, they usually had maids, nannies, slaves, butlers. It was customary not to raise their own children. Which means, it's not in our blood or in our history to have close familial ties.
And I look at African families, Aboriginal traditions, South American traditions – all that – that supported strong familial bonding. Bonding within the community, where children aren't raised by their parents alone but by entire villages. Not always, but sometimes.
Just a thought...
