Trump thinks economic growth is going to reach unprecedented levels...that’s just stupid..
Look at the economic growth numbers the NY Fed is now predicting. More than double anything Obama ever achieved.
The problems with all the organizations you cite is they base their models on very low GDP.
Trump's got the formula, the key is job growth which in turn creates upward pressure on wages. The story of Obama's economic failure is that labor participation was horrible and not reflected in unemployment numbers and wage growth was non-existent.
Solve those two labor problems and you have more people with larger disposable incomes which fuels major economic growth.
Everything I've seen for the last year points to Trump having a lot of economic success and GDP being extremely strong. This basically destroys any economic pessimism Dems are pushing on the new tax code we are going to have.
