beyond that , failure to raise the ceiling would mean missed payments on existing u.s. government debt . but a u.s. government default , which will happen unless congress raises the debt ceiling soon , might cause financial catastrophe . today we have a weak economy . so let ’s call these house republicans what they are , says jon favreau . on july 30 , 2011 , i began drafting an address to the nation about what would happen if congress refused to raise the debt limit within 48 hours , thus denying the united states treasury the ability to pay our country ’s bills for the first time in 235 years . photo still , a government shutdown looks benign compared with the possibility that congress might refuse to raise the debt ceiling . with each passing day , making our debt payments to businesses and governments around the world would become more and more difficult . every company in america that does business with the federal government , of which there are hundreds of thousands , would not see their contracts paid on schedule , an effect that would ripple down to their employees and their families . , a temporary government shutdown that will cause financial hardship and even ruin for millions of americans .
