... because you want to feel like a good parent.
Or so suggests this piece in The New York Times, which begins:
"When Donna Campiglia learned recently that a genetic test might be able to determine which sports suit the talents of her 2 ½-year-old son, Noah, she instantly said, Where can I get it and how much does it cost?"
I have said before that the reason why Feed is the best dystopic novel for young adults is because it captures so well how inclined humans are to clamor and even pay for the hallmarks of an Orwellian society, especially if it benefits their children--something neither Orwell nor Huxley quite captures. The government won't have to install the two-way TV in your house. You'll buy it and pay a monthly fee because you've heard it's got good programming for your toddler.
I don't mean to sound paranoid or generally anti-genetic testing. I'm not (as a parent, I can sympathize with this); but I find it fascinating and troubling that parenting and retail genetics are so often two peas in a pod.
