If anyone's interested, what Roosavelt did was create the federal reserve.
Hell people would be real damn interested in that, because it make FDR capable of time travel, allowing him to go back to 1913 - some 17 years BEFORE his inauguration - and magically act as President when in fact, someone else - Woodrow Wilson - was in that office at that time and promoted the very same legislation.
Of course it was hardly new, from 1791 to 1811 there was the First Bank of the United States followed by the Second Bank of the United States (1816–1836), an Independent Treasury System from 1846–1921, and true national banks beginning in 1863. If - since America has set this terrifyingly detrimental standard, other western countries have not found it alarming to become similarly hopelesly in debt - is true (and I'm not sold on that either), then it's their own fault, we've never said it was a model, we've always said it's an experiment.
