Deep Dive: Each State
Alaska (AK)
Tax reality
Alaska is a tax haven: zero state income tax, zero state sales tax (some municipalities add local sales tax), AND the Permanent Fund Dividend (PFD) pays every resident $1,000-$3,284 annually from oil royalties. A $100K salary in Alaska nets roughly $7,000+ more than Texas after PFD, despite higher cost of goods.
Top cities (1 tracked)
Top drawbacks
- ✕Winter darkness is psychologically brutal. Anchorage gets 6 hours of daylight in December, Fairbanks gets 3.5 hours, Barrow gets zero for ~2 months. Seasonal affective disorder is common. Winter depression and high suicide rates are documented realities.
- ✕Earthquakes are frequent and severe — the 1964 Great Alaska Earthquake was 9.2 magnitude (tied 2nd largest ever recorded). The 2018 Anchorage earthquake was 7.1 magnitude and caused significant damage. Building codes are strict but quake risk is real and insurance reflects it.
- ✕Cost of goods is 40-60% higher than the lower 48 — groceries cost ~$280/week vs $180 nationally. Eggs are $4-$6/dozen, milk $6-$8/gallon. Everything is either shipped by barge (slow, expensive) or flown. Remote villages are even worse ($400+ per week for basics).
Idaho (ID)
Tax reality
Idaho has a 5.8% flat state income tax (moderate). Property tax is low (~0.6% effective). Sales tax 6%. No estate tax. Overall moderate tax burden.
Top cities (1 tracked)
Top drawbacks
- ✕Housing growth has outpaced wage growth. Long-time Idaho residents have been priced out of Boise proper.
- ✕Summer wildfire smoke affects air quality regularly — July through September can have multiple weeks of AQI 150-200+.
- ✕Idaho is deeply conservative politically, with some policy shifts (abortion, LGBTQ+, religion in schools) recently tightening. Boise specifically leans moderate; the rest of the state is more conservative.
