I’ve read that President Hoover was just as much an activist, interventionist president as FDR. Popular legend holds that it was FDR that opened up federal spending and started the activism.
Haven’t done my own research until today. Check out page 21 of the 2013 federal budget, found here, to see the info for yourself. That is the 25th page of the PDF. Table 1.1 lists federal receipts, outlays and surplus/deficit by year from 1901 through the 2017 estimate.
Hoover dramatically increased federal spending and started the big deficit splurge well before FDR has a chance to get his New Deal spending plans in front of Congress.
Check out the following data, which is for fiscal years ending June 30. That means the 1929 budget went into effect on 7/1/28, well before the election. Thus, the 1930 budget is the first that we can attribute to Hoover. The 1931 budget is essentially the first that was drafted and approved in light of the developing depression. The 1934 budget is the first that belongs to FDR.
