History Repeats. Remember the Regan economy? It's been 25 years since we've had a pure unadulterated bull run (thanks to structural control) with a working-class train that cannot be halted.
Fundamentals: Huge job numbers = millions of shiny 401k's. Regulations and red tape being slashed like a fire-sale on black Friday. China deal (even though we don't need it) The lid is about to blow. Do I even need to mention the return of the strong USD? The key to long-lasting growth is to get a handle on the debt within the next 6 years, and eventually turn it into surplus (dividends for all?)
