Last month, we celebrated the anniversary of the Brown v. Board of Education ruling that officially outlawed school segregation — a pillar of America’s sacred promise to provide a quality public education to all children, regardless of their race, gender or family income.

And yet 65 years after Brown, that promise is being broken, as our nation’s schools are being battered by budget cuts, privatization schemes and resegregation. My Thurgood Marshall Plan for Quality Public Education for All aims to reverse this by reinvesting in our schools and combating the drivers of segregation.

Over the past few decades, public schools have endured massive budget cuts that often ended up paying for huge tax breaks to corporations and wealthy individuals. While companies like Amazon pay zero taxes, we are seeing mass school closures and dilapidated classrooms, especially among those in poor communities of color.

To combat this, my education plan calls for rescinding Donald Trump’s tax breaks and using those resources to triple funding for low-income school districts. We will also institute a national per-pupil funding standard, so that the quality of a child’s education is not contingent on her zip code. Education should be a human right, not a privilege.

In addition, my plan also calls for restrictions on charter school initiatives that siphon resources out of the public education system and resegregating schools.

When parents enroll their children in charter schools, the public funding allocated to those students goes with them. In the Oakland Unified School District, for example, charter schools were costing the district more than $57 million per year. This amount would easily cover the budget shortfall of $56 million over two years that Oakland officials have projected.

Charters are publicly-funded, but they are privately managed — meaning, they are not accountable to taxpayers. As a result, billionaires like Eli Broad, the DeVos family, and the Walton family are able to bankroll destructive charter school experiments to enrich investors and real-estate developers with taxpayer resources.

Between 2002-2017, California charter schools received more than $2.5 billion in tax dollars or taxpayer subsidized funds to lease, build, or buy school buildings. In one example, the Alliance Ready Public Schools network of charter schools used public funds to build a $200 million private real estate empire in Los Angeles. Meanwhile, a report from the Network for Public Education found 38 percent of California charter schools that received federal funds between 2006 and 2014 “had either never opened or shut their doors by 2019.”

Advocates argue that charters deliver good outcomes — but the overall results are mixed at best.

Take Betsy DeVos’s home state of Michigan, where she pushed a huge expansion of charter schools. That expansion coincided with Michigan declining to the bottom for reading on national tests.

Charters also have poor outcomes when it comes to school segregation. A 2017 Associated Press report found that while 4 percent of traditional public schools are 99 percent minority, the figure is 17 percent for charters.

My education plan calls for a ban on for-profit charter schools and a moratorium on federal funding of new charters until we can ensure they’re operating with transparency and accountability.

I am proud to stand with the NAACP, the Movement for Black Lives, the Los Angeles Unified School District, the United Teachers Los Angeles, and the Los Angeles school board in supporting this moratorium, and I applaud California lawmakers for trying to pass legislation to restrict charter school growth.

Sixty-five years after the Brown decision rejected the idea of “separate but equal,” we must reject charter schemes that aim to create a parallel school system to compensate for lack of investment in our public schools,Instead, we must defeat Trump in the election, and commit to providing good quality education to all.
