than that it is a magic trick". According to Stein, the Federal Reserve could buy up student loans and agree not to collect the debt, thereby effectively canceling it. Because the Federal Reserve is an independent government agency, the president lacks the authority to implement such a plan. Stein has drawn parallels between her student loan proposal and the Wall Street bailout, saying that the US government bought up Wall Street debt and then canceled it. Jordan Weissmann of Slate argues that Stein's Wall Street comparison is "flat wrong": the Federal Reserve did not buy and cancel debt owed by the banks but bought and held onto debt owned by the banks. When asked why her plan includes canceling upper-income individuals' debt, Stein responded that higher education "pays for itself" and that education is not a "gift," but a "right," and a "necessity." Stein feels that the move towards computerized education in kindergarten was bad for young children's cognitive and social development, saying, "We should be moving away from screens at all levels of education." She argues that increasing computerization benefits only device manufacturers, not teachers, children, or communities. Stein opposes charter schools and has been critical of the Common Core, saying that teachers rather than "corporate contractors" should be responsible for education. Electoral reform Stein is critical of the two-party system, and argues for ranked-choice voting as a favorable alternative to "lesser evilism". Calling for "more voices and more choices", the Stein campaign launched a petition demanding that all candidates appearing on a sufficient number of state ballots to be theoretically electable should be invited to participate in the presidential debates. In September 2016, Stein announced support for lowering the voting age to 16, in line with many other Green parties worldwide. Energy and environment Stein proposes that the United States shift to 100% renewable energy by 2030. She supports a national ban on fracking on the grounds that "cutting-edge science now suggests fracking is every bit as bad as coal". She has spoken against nuclear energy, saying it "is dirty, dangerous and expensive, and should be precluded on all of those counts." In March 2016, she tweeted, "Nuclear power plants = weapons of mass destruction waiting to be detonated." In 2012, Stein said, "three times more jobs are created per dollar invested in conservation and renewables. Nuclear is currently the most expensive per unit of energy created." Stein
