Six Economic Policies Advocated by Economists but are Politically Toxic

According to NPR's Planet Money show, there are six economic policies "backed by economists of all stripes, but probably toxic to any candidate that might endorse [them]." They are (slightly rephrasing for brevity):

1. Eliminate the mortgage tax deduction;
2. End businesses' employee health care tax deduction;
3. Eliminate the corporate income tax;
4. Replace all income taxes with progressive consumption taxes;
5. Tax carbon emissions (have a gas tax); and
6. Legalize and tax some or all narcotics.

Here's a Planet Money podcast this relates to. And I'm not opposing or advocating any of this; just reporting.
