Roosevelt's "Three R's" administration programs were put in action in the midst of the Great Depression with the aims of solving the crisis by introducing a series of laws that focused on immediate issues such as mass unemployment; and more large-scale problems like industrial recovery and balancing of the market.
This should serve as a good summary for what each theme standed for along with a few concrete examples:
<u>Relief</u>: Giving away immediate and direct aid to the most empoverished portions of the population who were also unemployed and thus at severe risk (<em>the Federal Emergency Relief Act granted funds for various relief projects</em>).
<u>Recovery</u>: Helping businesses reconstruct in order to create job opportunities, reactivate consumer demand, and restart the flow of the market (<em>the Reforestation Relief Act introduced the Civilian Conservation Corps, for example, adressed an urgent structural problem while giving work to over 200,000 people</em>).
<u>Reform</u>: A long-term re-thinking of how the financial system should work so that future economic crisis could be avoided (<em>the Emergency Banking Relief Act was created to regulate the Banking system</em>
).
Hope this helps!
