OP, hint, it's not the President nor government's job to help the poor.
I never said it was

I believe that the free market helps the poor the most.
A lot of FDR's supporters were wealthy and FDR hurt the poor by getting off the gold standard and stimulating the great depression. He also created the most regressive tax in history and put the country further into debt. All that bastard had to do was go to a gold coin standard, get rid of the Fed, and establish a national 100% reserve mandate while creating bankruptcy legislation that forgave a fraction of private debt. If he did all of that and lowered taxes, the market would've corrected itself from there and we probably wouldn't have been in so much debt.
LBJ's medicare somewhat raised the cost of health care and he likely created many more poor people. He also spent so much that Nixon felt it necessary to get completely off the last remnants of the gold standard. His Fair Housing Act certainly didn't help many poor white people either.
