Various studies have shown that children raised by a single mother comprise about 70% of juvenile murderers, delinquents, teenaged mothers, drug abusers, dropouts, suicides and runaways. Imagine an America with 70% fewer of these social disorders and you will see what liberals' destruction of marriage has wrought.
A 1990 study by the (liberal) "Progressive Policy Institute" showed that, after controlling for single motherhood, the difference in black and white crime rates disappeared.
Meanwhile, adopted kids, on average, turn out better than even biological kids raised in two-parent families.
Of course, there aren't a lot of studies of adopted children because they aren't constantly mugging us. They're too busy running Oracle (Larry Ellison), the District of Columbia (Anthony Williams), or fantastic political websites, like "Big Government" (Andrew Breitbart).
One four-year study by the Search Institute in Minnesota found that adopted teenagers had greater empathy, higher self-esteem and more close friends than non-adopted teenagers in public schools, and were also less likely to engage in high-risk behavior, such as stealing and excessive drinking. In all, they scored higher than the control group on 16 indicators of well-being.
They were as strongly attached to their parents as their non-adopted siblings. Indeed, contrary to Hollywood movies portraying adopted kids mystically driven to find their biological parents, the majority of adopted teenagers rarely thought about the fact that they were adopted. (Apple's Steve Jobs has shown little interest in his biological father and corrects people who refer to his "adoptive parents," saying, "They were my parents.")
We could wipe out chronic poverty in America tomorrow -- and the new iPad would be even more awesome, if such a thing were possible! -- if only women would get married before having children or give up their illegitimate kids for adoption.
And yet, between 1979 and 2003, we went from about 600,000 babies being born out of wedlock, with about a quarter of them put up for adoption, to 1.5 million illegitimate births with fewer than 1% of them (14,000) given up for adoption. That's why Angelina Jolie and Madonna are constantly having to break up tribal wars to adopt Third World children.
A 2008 study led by Georgia State University economist Benjamin Scafidi conservatively estimated that single mothers cost the U.S. taxpayer $112 billion every year -- in addition to asking the rest of us to keep an eye on their kids while they go clubbing.
We could have had two Iraq wars -- Obama could have "saved or created" half a million stimulus jobs -- at that price.
But in fact, Scafidi underestimated single mothers' burden to society by excluding additional costs of single mothers to poverty programs such as the Earned Income Tax Credit.
That makes his estimates very low: Single mothers are six times more likely to be in poverty than married families. More than 80% of homeless families are single mothers.
Scafidi's study also did not consider the burden single mothers place on law enforcement because of their higher likelihood to neglect or kill their children.
85% of mothers who kill their children through neglect are single mothers.
The plague of single motherhood isn't an inevitable decay brought on by stupid choices of the underclass.
Destroying the family is the active social policy of liberals.
They enjoy experimenting with other people's lives and leaving the taxpayer with the bill.
