Kennedy's assassination in 1963 spurred Congress to enact much of his legislative agenda. His successor, Lyndon Baines Johnson (1963-1969), sought to build a "Great Society" by spreading benefits of America's successful economy to more citizens. Federal spending increased dramatically, as the government launched such new programs as Medicare (health care for the elderly), Food Stamps (food assistance for the poor), and numerous education initiatives (assistance to students as well as grants to schools and colleges). 

     Military spending also increased as American's presence in Vietnam grew. What had started as a small military action under Kennedy mushroomed into a major military initiative during Johnson's presidency. Ironically, spending on both wars -- the war on poverty and the fighting war in Vietnam -- contributed to prosperity in the short term. But by the end of the 1960s, the government's failure to raise taxes to pay for these efforts led to accelerating inflation, which eroded this prosperity. The 1973-1974 oil embargo by members of the Organization of Petroleum Exporting Countries (OPEC) pushed energy prices rapidly higher and created shortages. Even after the embargo ended, energy prices stayed high, adding to inflation and eventually causing rising rates of unemployment. Federal budget deficits grew, foreign competition intensified, and the stock market sagged. 

     The Vietnam War dragged on until 1975, President Richard Nixon (1969-1973) resigned under a cloud of impeachment charges, and a group of Americans were taken hostage at the U.S. embassy in Teheran and held for more than a year. The nation seemed unable to control events, including economic affairs. America's trade deficit swelled as low-priced and frequently high-quality imports of everything from automobiles to steel to semiconductors flooded into the United States. 

     The term "stagflation" -- an economic condition of both continuing inflation and stagnant business activity, together with an increasing unemployment rate -- described the new economic malaise. Inflation seemed to feed on itself. People began to expect continuous increases in the price of goods, so they bought more. This increased demand pushed up prices, leading to demands for higher wages, which pushed prices higher still in a continuing upward spiral. Labor contracts increasingly came to include automatic cost-of-living clauses, and the government began to peg some payments, such as those for Social Security, to the Consumer Price Index, the best-known gauge of inflation. While these practices helped workers and retirees cope with inflation, they perpetuated inflation. The government's ever-rising need for funds swelled the budget deficit and led to greater government borrowing, which in turn pushed up interest rates and increased costs for businesses and consumers even further. With energy costs and interest rates high, business investment languished and unemployment rose to uncomfortable levels.
