Six months? Maybe.
If Romney and congress:
1) Flat tax or Fair Tax
2) cut 33% spending ASAP
3) deregulate the energy
...our economy will BOOM.
But I don’t expect the above 3 to happen.
Even simply refraining from monkeying with Bush-era revisions to the tax code, would be of some help. Any transition to flat or “fair” tax would need several years to avoid throwing those who depended on the old code’s loopholes utterly into the lurch. It couldn’t happen that quick.
