The UK barely increased spending during the Great Depression - whereas America VASTLY increased spending.
What was the result?
America took about 10 years to get back to it's pre-crash GDP per capita.
The UK - only about 4 or 5 years.
America took about 14 years to get it's unemployment rate back to pre-crash levels.
The UK - only about 9 or 10 years.
So, despite the fact that the U.S.A. spent TONS of money and the UK almost nothing to combat the Great Depression - the UK seemed to recover from it FAR quicker.
Additionally, if the theory goes that the New Deal was responsible for the 'speed' (laugh laugh) of the recovery from the Great Depression? Then the UK - with it's virtually zero increase in spending - should not have recovered from their problems nearly as quickly - if virtually at all.
Yet they recovered FAR quicker.
