WASHINGTON (AP) — Calling for a "new college compact," Hillary Rodham Clinton on Monday will unveil a $350 billion plan aimed at making college more affordable and reducing the crushing burden of student debt.At a town hall meeting in New Hampshire, the state with the highest average student debt in the country, Clinton will propose steps to reduce the cost of four-year public schools, make two-year community colleges tuition-free and cut student loan interest rates, according to campaign aides.The college affordability plan, a main plank of her policy platform, is an effort to address a major financial stress for many American families and satisfy a central demand of the Democratic party's liberal wing.The proposal centers on a $200 billion federal incentive system aimed at encouraging states to expand their investments in higher education and cut student costs.
