Student loan forgiveness is simply a bribe for voters to vote for Democrats in upcoming elections. Besides the fact that it will hurt America's taxpayers more than anyone else, the move could easily backfire for Democrats by driving up inflation and further damaging the economy.
Student loan forgiveness could be a simple way of creating more equity in American society and even actually stimulate the economy by helping young people struggling under the burden of large debts. Student debt has disproportionately hurt Black Americans. Forgiveness would "even the playing field" for all Americans.
Though student loan forgiveness could be an effective and moral policy, SCOTUS could very likely make such a move a moot point anyway. The court has shown a clear recent pattern in limiting executive power.
