Everyone young and upwardly mobile is at least somewhat likely to become an entrepreneur AND a single parent. Entrepreneurs often need, er, seed funding.
From a January 6, 2010 article in Time magazine:
"A new science called epigenetics...is the study of changes in gene activity that do not involve alterations to the genetic code but still get passed down to at least one successive generation....Epigenetic 'marks'...tell your genes to switch on or off, to speak loudly or whisper....Through epigenetic marks...environmental factors like diet, stress and prenatal nutrition can make an imprint on genes that is passed from one generation to the next."
From 2010 book The Genius in All of Us -- Why Everything You've Been Told About Genetics, Talent and IQ is Wrong:
"If a geneticist had suggested as recently as the 1990s that a twelve-year-old kid could improve the intellectual nimbleness of his or her future children by studying harder now, that scientist would have been laughed right out of the conference hall. Today, that preposterous scenario looks downright likely."
From a 2004 email sent to me by the then-CEO of an Amazon-funded startup:
"I just spent about an hour surfing around [your business plan for establishing the eBay of customized education] with a bit of amazement."
