There's no way an income tax could make up for the lost tax revenues caused by the generalized commodities slump, especially when retail is a lower income sector. Healthcare is growing, but a lot of that growth is due to aging populations, which depend on publicly-funded insurance. The loss of insurance through employment for those in oil/gas as well as state government poses is a downward risk for that sector since private insurance companies' reimbursement rates are much more generous than those of Medicare/Medicaid.
