Democratic presidential candidate Elizabeth Warren has rolled out a plan that promises to make child care more affordable, as she aims to address a major pocketbook issue for parents.

The Massachusetts senator’s Universal Child Care and Early Learning program would provide free child care to families whose earnings are below two times the federal poverty level, according to her blog post on Medium.com.

The federal poverty level ranges from an annual income of about $21,000 for a family of three to about $35,000 for a family of six.

For families earning more than two times the federal poverty line, Warren’s plan would cap the cost of child care at no more than 7% of that family’s income, she said.

Warren has given examples of how families might benefit, saying a couple in South Carolina making $50,000 a year and raising a 4-year-old and an infant would get free child care for those two kids, rather than pay $11,000 a year, the average cost for such care in that state. A married couple in New Hampshire with two small kids making $125,000 would pay no more than $8,750 for child care, rather than shell out $21,000, the average cost in their state.

The senator said the federal government would partner with local partners to create a network of child-care providers that meet national standards. She said her program would be similar to the child-care program that the American military currently offers.

When it comes to how her plan would get funded, Warren said her so-called ultra-millionaire tax would cover all costs. That levy, which she proposed last month, would amount to a new 2% fee on U.S. households with net worth greater than $50 million, and it rises to 3% for net worth greater than $1 billion. Her economists project the tax would raise $2.75 trillion over a decade and hit less than the top 0.1% of household.

“In the wealthiest country on the planet, access to affordable and high-quality child care and early education should be a right, not a privilege reserved for the rich,” Warren wrote in her blog post. The child-care and preschool workers would be paid like comparable public-school teachers, she also said.

Other politicians aiming to become the Democratic Party’s 2020 presidential nominee also have stressed the importance of making child care more affordable, with New York Sen. Kirsten Gillibrand backing legislation on the issue, and former Housing and Urban Development chief Julian Castro promising “pre-K for the U.S.A.” The left-leaning People’s Policy Project think tank on Friday proposed a nationwide “Family Fun Pack” benefits package that would include free child care, saying progressive candidates would be wise to consider adopting it.

Meanwhile, President Donald Trump in his State of the Union address this month talked up the recent doubling of the child tax credit, as well as his plan for nationwide paid family leave.
