If we woke up tomorrow and the debt was gone? Assume nothing else has changed, ie. millions are unemployed or underemployed, and big companies are still sitting on their record cash reserves...
Assuming a steady budget deficit (unlikely) we'd be right back where we our now, in terms of debt, in roughly nine years. If you wanna dream, dream no debt AND no deficit.
In your imaginary world, the right thing to do would be to go reallocate incoming cash to spur REAL stimulus through tax incentives and domestic protection (vs. foreign investment). That would be my call.
Re the tax incentives part, for whom exactly? At the bottom, the unemployed, the underemployed, the unemployable, they pay little to no tax. At the top, the 1%'rs, they're not hurting. For businesses at the bottom, sales are down so naturally so are their taxes. For big businesses, deductions, exemptions, and offshoring have minimized their tax burdens and they have big cash holdings. So who is to get, and what kind are they, these "tax incentives", and how would they help?
