Is the rising federal debt going to hurt the stock market?

U.S. federal debt has risen  for decades. However,  not all debt is created equal. Falling interests rates may be mitigating some concerns around ballooning national debt.

“U.S. Government debt has increased nearly 800% since 1990. However, interest payments on this debt have increased only 145%. It may be that markets are not deterred by mounting U.S. debt because this debt is borrowed at lower interest rates, and thus the payments on the debt will be less onerous to tax payers” -Dean Bennion
