Interesting thread that sent me down the rabbit whole of Google for fact checking. Idaho is rated high as far as having a balanced, stable government with a ranking of #2 by US News. That is good news but before you dis too much on Washington you need to realize that they are ranked #4 in the country in the same poll. Washington has no income tax, Idaho does. Idaho has no estate tax, Washington does. Both have sales and property tax. They all tax you, just in different ways.
Looks like #50 New Jersey is the absolute worst place to live as far as taxes go.
