life expectancy of their voters, right-leaning parties will continue to have a strong base of support. When the 'Golden Age' of economic boom finally came to a grinding halt in the 1970s, various reforms were introduced. High-skilled workers earned even more than before whereas low-skilled workers saw their fortunes melt away and consequently became dependent on welfare. This created a schism between the two groups, with the upper-end of the working class now supporting the political Right upon realizing that it was they, as hard-working taxpayers, who were the ones financing welfare, something they would rather do without except in cases of emergency. The fact that some governments incautiously made such welfare programs quite generous during the boom years exacerbated resentment for 'the underclass'. Public housing complexes became nothing more than residences for those who were socially problematic and chronically dependent on welfare. Key generation milestones In a 1985 study of U.S. generational cohorts by Schuman and Scott, a broad sample of adults was asked, "What world events over the past 50 years were especially important to them?" For the baby boomers the results were: Baby Boomer cohort number one (born 1946–1955), the cohort who epitomized the cultural change of the 1960s Memorable events: the Cold War (and associated Red Scare), the Cuban Missile Crisis, assassinations of John F. Kennedy, Robert Kennedy, and Martin Luther King, Jr., political unrest, the Apollo Program, military draft, the Vietnam War, sexual experimentation, drug experimentation, the Civil Rights Movement, environmentalism, the second wave of feminism, and the Woodstock Festival. Baby Boomer cohort number two (born 1956–1964), the cohort who came of age in the "malaise" years of the 1970s Memorable events: the Cold War, the Cuban Missile Crisis, the assassinations of John F. Kennedy, Robert Kennedy, and Martin Luther King, Jr. (for those born in the first couple of years of this cohort), the Vietnam War, walk on the Moon, the Watergate scandal and Richard Nixon's resignation, lowered drinking age to 18 in many states from 1970 to 1976 (followed by raising back to 21 in the mid-1980s as a result of congressional lobbying by Mothers Against Drunk Driving (MADD)), the 1973 oil crisis, raging inflation, economic recession and lack of viable career opportunities upon graduation from high school or college, Jimmy Carter's reimposition of registration for the draft, the Iran hostage crisis, the election of Ronald Reagan as president, and Live Aid.
