(CNN) Sen. Elizabeth Warren has big plans for America.

If she's elected president, the Massachusetts senator would provide free health care for everyone. She would wipe out student loan debt for tens of millions of people and give free child care to millions of kids. She would increase Social Security benefits by $200 a month and invest heavily in clean energy technology.

These big ideas -- along with others the 2020 Democratic candidate has announced -- come with an equally big price tag: More than $30 trillion over 10 years.

If enacted, her proposals would balloon federal spending by more than 50% over a decade -- on top of the nearly $58 trillion already projected by the Congressional Budget Office. To pay for it, Warren would increase taxes on the wealthy, corporations and Wall Street, while expecting employers and states to chip in too.

"She's got a very, very ambitious -- you might almost call it a muscular -- program of what government should do," said William Gale, senior fellow in economic studies at the Brookings Institution. "It's firmly based on the idea that some problems lend themselves to government solutions better than others do. It's a no-apologies approach to policy."
