If the New Democrats had their way, we might slap a bandaid onto one or two issues while otherwise plugging their ears and ignoring the rot. They are not addressing the main issue. In those few cases where they do apply the bandaid, the incrementalist approach sees and will see the result torn down by a republican party that screams "socialism" one two or three elections later because they ignored the bold, and more importantly popular policy that could have been put into place.
2008-2016 in a nutshell basically.
1. Financial crisis ensues.
2. Beg Mr. Bernanke to fix it.
3. Congress bails out the banks and auto industry after Bernanke had exhausted everything in his toolbox at the Fed.
4. Call it a day and keep most of the pre-2008 system chugging along.
5. Disgruntled working people turn to a populist demagogue in Trump. Brexit. The rise in political power of populist Parties all across the OECD, etc.
