The Planet Money team got together a group of economists from widely differing political backgrounds, and came up with this very nice list of policies the economists all agreed on--which are all regarded as hopeless in the standard political debate.
- Eliminate the mortgage tax deduction.
- End the tax deduction companies get for providing health-care to employees.
- Eliminate the corporate income tax. Completely.
- Eliminate all income and payroll taxes. ... Instead, impose a consumption tax.
- Tax carbon emissions.
- Legalize marijuana.
(I quoted the proposals as above. In fact, the health tax exemption applies to individuals, and it's for employer-provided group health insurance, not care. Hat tip, I found the NPR story in a nice post on econlog)
