Growing the economy can take years, and there is no clear path on how to do it. Meanwhile, we will still be out of sync. I think we need all three -- raise taxes, cut spending and increase the GDP. Congress can't quickly do anything about the GDP, but they can affect the other two. Congress is more interested in getting reelected than doing anything.
I do not believe your statement is accurate in an historical sense. History shows that economic growth can come quickly. If you look at what Coolidge, JFK, and Reagan did, you see that economic growth during their terms was very good. And conversely, economic growth was poor during Hoover, FDR and BO's presidencies.
Below is a comparison of GDP growth rates between Reagan's first term and BO's.
We had GDP growth averaging 7% by Reagan's fourth year. I think that rather quick. If we had that rate today, instead of 2.5%, revenues would be flowing into the Treasury and things would not be so bleak.
It comes down to the policies of the administration. The burdensome policies of BO will NOT generate significant economic growth no matter what tax and spend policies are implemented. However, BO policies while not helpful, can be very damaging very quickly. BO is following in the footsteps of FDR...he admits doing so. Yet history shows FDR a complete economic failure who caused great harm.
Why has BO chosen to impose harmful economic policies? I think the answer is simple. He is a collectivist first and foremost who knows little about economics just like FDR.
BO intends to impose EVEN MORE regulations on the private sector...and 2700 pages of new regulations in Obamacare has yet to kick in....the consequences of collectivist economic policies will be a continued weak economy, low GDP growth, and high unemployment.
