Margret Thatcher did succesfully tame excessive inflation rates through the use of monetarist polices. However, this came with the oppertunity cost of rising unemployment as well as a shift away from the industrial sector. During Thatcher's premiership coal production fell drastically, reaching the lowest point in 1984 shortly after the battle of Orgreave. Rising unemployment and economic reallignment during this period prevented Britain from achieving a real GDP output which rivalled the previous prosperity of the 50s and 60s.
