The United States has faced a series of major economic issues in its  history, the two most commonly discussed are the Great Depression (1929  to 1942 arguably) and the Great Recession (2008 – 2009 officially) but  between those two is a lumpy, difficult to fathom, general economic  decline that ran from 1971 until roughly 1982 which could be considered  the Great Stagflation.  It was the hallmark of the 1970s United States  economy, with a solid impact on the British economy as well.  Within the  United States it was caused by an intersection of several different  policy issues, economic impacts, and major events, such as the two oil  shocks that took place in that decade as OPEC reduced oil production in  response to the United States’ position towards Israel.

Nixon, who had a very loose concern for domestic economic issues, made  the problems worse when facing the gold crisis of 1971.  Briefly the  United States pegged the dollar to a fixed conversion rate and other  currencies were fixed to the United States dollar.  During the early  1970s the dollar ended up being worth less in actual goods and services  than its fixed gold value, leading to other nations beginning to convert  their dollar holdings into gold.  Nixon nipped that problem by simply  ending the gold conversion of dollars “temporarily” and then imposing  price controls to take the sting out of the sudden devaluing of the  United States dollar as foreign governments dumped their now  non-convertible dollars.  This was fine for Nixon, he was facing  re-election in 1972 and he simply wanted domestic voters to feel that  their paychecks remained the same, it didn’t matter to him what happened  to the economy post-1972 as much, he simply planed to fix it then.

One of the impacts of this, and other factors such as rising foreign  competition that cut the United States share of global trade, spiked  inflation rates.  This combined though with an unusual factor, as rising  inflation eroded the buying power of domestic wages in the United  States, organized labor was powerful enough to demand wage increases  from companies to offset the inflation.  This reduced the amount of  capital available for investment and the economic instability and  uncertainty that rising inflation caused discouraged many businesses  from entering into any major investments.  This led to economic  stagnation, the production of goods and services simply didn’t expand to  meet the growing money supply, which caused shocking inflation rates.   (During the height of the crisis inflation rates of 10% were not  uncommon in a single year.)

Normally economic cycles tweak the system, but the events of the 1970s  reshaped the United States economic and political landscape.  First,  rising inflation pushed up the tax brackets which working and middle  class employees were taxed at, as the brackets were not indexed in the  1970s to inflation.  So although the relative buying power of a paycheck  remained the same, the bite taken out by state and local taxes went up  for many workers, reducing their overall net pay.  This combined with  many states reporting record surpluses due to the revenues taken in, and  a resistance by those state governments to return the surpluses to the  voters.  (California was notorious for this, socking away much of the  surplus for future anticipated shortfalls or new programs once the  economy settled down.)  Property taxes shot up as well, as the paper  value of homes skyrocketed due to inflation and people saw their  property tax bills rocket upwards, further reducing their buying power.

The result was a general tax revolt across the United States as  citizens, in state elections and in 1980 with the election of Ronald  Reagan and a Republican Congress, demanded their tax burden be lowered.   What made this shift particularly unique though was that prior to the  late 1970s and early 1980s the United States populous had been less  leery of inflation, and higher taxes, and more leery of the government  reducing its safety nets.  By the height of this crisis the United  States citizenry had changed their demands, inflation control and lower  taxes were more critical to them than safety nets, especially safety  nets that seemed to re-route funds from middle class pockets to the  poor, minorities, and immigrants.

Which state governments, and the federal government, responded to with  great gusto.  The federal government, and state governments, slashed  social welfare programs aggressively and changed the regulatory client  to make the government more pro-business.  This combined with a focused  effort to reduce the power of organized labor and allowing unemployment  to spike, and a sharp early 1980s recession, to crush inflation.  In  many ways since then the United States as a nation has not looked back,  and other nations have followed its model, focusing on tight government  services, reduced social support for the lowest portions of society, and  keeping the tax burden controlled.
