"On Tuesday, Sen. Elizabeth Warren (D-MA) introduced a bill addressing two of her top legislative priorities: The crushing burden of student debt and tax loopholes that allow the wealthiest Americans to shell out a smaller share of their incomes than do many of those in the middle class. The measure would allow people who took out student loans at a higher rate than they could get today to refinance their debt the same way one might refinance a home mortgage. It would also give people with high-interest private loans to roll them over into the Federal Direct Loan program."
