Answer:
The New Deal legislation was so effective, that it earned FDR the rank of one of the best U.S. presidents in history. Frankly, I’d agree!
So this New Deal basically added a mass amount of manual labor jobs along with other blue collar work. At the time, people were not complaining, they needed jobs in order to survive. It very well did succeed in boosting the economy because not only did it give jobs to those that needed it; but it also ended up creating roadways and buildings useful to the American people for years to come.
A great comparison is Eisenhower’s road system that funded many American people. This mass road system created jobs and is still used to this very day.
Hope that helps! Have a good one!
