The Fifties, or the US prior to its 60s upheavals; a.k.a. "Ozzie & Harriet", after another top TV show of the era. The years of the television-idealized American nuclear family (led by a breadwinner and his housewife) - a "world" referenced when "family values" is invoked, a lost utopia we must regain. Of course, there was lots of drug use, underage drinking, premarital sex, and the like; today's lack of shotgun weddings only makes it seem like teen pregnancy is a modernist ill.
