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).

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 prosperityMany Americans feared the hard times of the Depression might return with the end of huge military expenditures. But, responding to pent-up consumer demand, the U.S. economy experienced exceptionally strong economic growth in the postwar period.
