First, 40% goes out of the united states. Much of the interest held by Americans is paid to high income Americans and does not return to the demand side. Poor people and middle income Americans do not hold a lot of the debt. The interest on the debt comes off the top and will take the general fund money needed for Social Security, Medicare, education and defense. It is not a doomsday scenario it is not a sound fiscal policy. The Fed Chairman is continually warning of the debt as did former Sec O'Neil. No person, company or nation can continually go into debt. The interest is a nonproductive component of the budget and does does not pay for any needed services. It is in essence paying for years of spedingt more then we taxed. There is no sound reason, given the fact that we are in a recovery, to be experiencing annual deficits of almost a half trillion dollars. What we are doing is mortgaging the future to pay for the past simply because we do not have a fiscal discipline to pay for what we want. To put ourselves in a position where the interest each year is equal to or greater than the amount we spend on national defense or on all other non-defense non entitlement programs is totally irresponsible.
