There was a time when the phrase "American family" conjured up a single, specific image: a breadwinner dad, a homemaker mom, and their 2.5 kids living comfortable lives in a middle-class suburb. Today, that is no longer the case, due to divorce rates, single parenthood, and increased out-of-wedlock births. Most Americans fail to identify the root factor driving the changes: economic inequality that is remaking the American family along class lines.
