“A default could potentially — but not necessarily — delay the payment of Social Security benefits, which reach about 65 million Americans in some form,” the Times said. “It could also delay payments to government contractors, including hospitals that accept patients who use Medicare and Medicaid benefits.” A default would also have effects that trickle down further, including to state-run programs, as well as the expanded child tax credit. The next scheduled payment from that is October 15, which is before the possible default date, although another payment is due November 15.
