This is not a matter of any generation’s having to “lower its sights,” to use President Obama’s words, nor is it a denial that some children of lower- and middle-class parents will, through talent and/or good fortune, strike it rich and bound precipitously into the upper class. Nor is it a moony, nostalgic wish for a return to the scrappy 30s or the suburban 50s, because any sentient person recognizes that there’s plenty about the good old days that wasn’t so good: the original Social Security program pointedly excluded farmworkers and domestics (i.e., poor rural laborers and minority women), and the original Levittown didn’t allow black people in.
But those eras do offer lessons in scale and self-control. The American Dream should require hard work, but it should not require 80-hour workweeks and parents who never see their kids from across the dinner table. The American Dream should entail a first-rate education for every child, but not an education that leaves no extra time for the actual enjoyment of childhood. The American Dream should accommodate the goal of home ownership, but without imposing a lifelong burden of unmeetable debt. Above all, the American Dream should be embraced as the unique sense of possibility that this country gives its citizens—the decent chance, as Moss Hart would say, to scale the walls and achieve what you wish.
