‘Reagan, Obama and Inequality’

Nicholas Kristof, writing for the New York Times:

Obama rightly heralded the fall in teenage pregnancy rates. But he had little to do with it (although the MTV show “16 and Pregnant” played a role!), and about 30 percent of American girls still get pregnant by age 19. Making reliable birth control available to at-risk teenagers would help them, reduce abortion rates and even pay for itself in reduced social spending later.

30%?
