What the economy needs first is a recession. A good recession will give a chance for all the malinvestments to be flushed out of the economy and all the bad economic decisions made over the years provided it's allowed to run its normal course. The problem with the Recession in 2000 and the one in 2008 was, instead of letting them work themselves out, we had more bubbles, stimulus, and just general bad policy. We also ended up with an overvalued, rigged Stock Market and manipulated interest rates
The problem is Trump wants more stimulus. The GOP in Congress need to resist that. There also needs to be cuts in federal spending. Not just slowing in deficit spending or debt accumulation, but real, deep cuts across the board in spending. The growing debt will drag down real, sustained economic growth.
If the GOP goes along with Trump's spending desires, we will, at some point, see another situation repeated as happened in 2006 and then especially in 2008 were the GOP ended up losing everything
