2020 presidential election: Elizabeth Warren's $640 billion student debt proposal

By the numbers: Warren's plan would eliminate all federal and private student loan debt for more than 75% of the 45 million Americans who currently hold loans. It also would include universal free public college.

• Every person with a household income under $100,000 would be eligible for $50,000 in debt forgiveness — those above that threshold would lose $1 of debt forgiveness for every $3 more they earn.
• Those whose household income is more than $250,000 do not qualify for any forgiveness.
• The plan would also create a fund of at least $50 billion to aid historically black colleges and universities.
