WPA:
As the Great Depression worsened, unemployment skyrocketed, and many began to ask, "How will the jobless get enough food to eat? What should be done about relief?"
Well, traditionally it is charity that helped those in need. The Founders all saw relief as local and voluntary, and the Constitution didn't give the federal government a role in charity. Madison said, "No man is allowed to be a judge in his own cause, because his interest would certainly bias his judgment and, not improbably, corrupt his integrity." Madison also asked, "What are the different classes of legislators but advocates and parties to the cause which they determine?"
The Red Cross and Salvation Army were set up in the 1800s to help people in hard times. Congress was tempted several times to play politics with charity. In 1887 a few counties in Texas lost crops due to a drought. Texas politicians helped cajole Congress into granting $10,000 worth of free seeds to the farmers. After it passed, Grover Cleveland vetoed it, "I can find no warrant for such an appropriation in the Constitution...[such aid would]...destroy the partitions between proper subjects of Federal and local care and regulation. Federal aid, in such cases encourages the expectations of paternal care on the part of the Government and weakens the sturdiness of our national character." Cleveland concluded, "the friendliness and charity of our countrymen can always be relied upon to relieve their fellow citizens in misfortune."

I have a lot of other examples but thats the gist, the WPA was just a leap into the arms of paternalism and furthered the decay of self responsibility. Sure, times are hard, but the Government has no business taking care of you. If it did, there would be an amendment.
Thus, the WPA may have helped people, but in the long run it hurt the "sturdiness of our national character" exactly how Cleveland said it would. The ends don't justify the means in this case.
