When Congressional Democrats began the legislative process to enact President Biden’s Build Back Better agenda last month, Sen. Bernie Sanders insisted on adding a costly expansion of Medicare benefits to the bill. But a new report from the program’s trustees makes clear that this expansion would be unwise: Medicare is already expensive and growing faster than the revenues needed to finance it, resulting in unsustainable deficits. Before Washington considers adding benefits that would further increase costs, it must find a way to pay for the promises it’s already made. Otherwise, critical public investments in young Americans and working families in greater need could be crowded out.
