Your model is consistent? So what? In the realm of science it ought to be considered of little or no value to simply make claims about the model and lose sight of reality. There is a difference between having evidence for some hypothesis and having evidence for the hypothesis relevant for a given purpose.

Brad DeLong admits neoliberal era has come to an end Should Democrats lean away from market-friendly stances and get comfortable with big government again? Should they embrace an ambitious 2020 candidate like Sanders and policies like the Green New Deal, or stick with incrementalists like former Vice President Joe Biden and more market-oriented ideas like Obamacare?
