Ron Paul, a candidate for the Republican presidential nomination, has called for ending the federal student loan program, saying that it has "failed," the Associated Press  reported. Paul said that government programs have forced up tuition rates. "Just think of all this willingness to want to help every student get a college education," said Paul, who graduated from Gettysburg College and then earned a medical degree at the Duke University. "I went to school when we had none of those. I could work my way through college and medical school because it wasn't so expensive."
