The article is mostly about how the shale oil/fracking boom has enriched some Texas counties. I found more interesting the following:
Fairfield County, Conn., topped the list in 2005, followed by Teton County in Wyoming (home of wealthy enclave Jackson Hole), and they were subsequently in the top 5 for the next few years, according to the Transactional Records Access Clearinghouse (TRAC), which collects data from the IRS.I live one county south of Teton County. As you might imagine, many people who have everyday jobs in Jackson can't afford to live there. Commuting 30+ miles each way isn't fun in the mile-high Rocky Mountain winter.
But as of 2015, the most recent year for which data is available, only one of them is still in the top 5: Teton County, where the average adjusted gross income was $248,949.
Jackson has one of the most scenic airports in the nation; in summer there are normally 25-30 executive jets parked on the apron. Wisecrack common among real estate pros in Jackson Hole: The billionaires are buying out the millionaires. Not a huge exaggeration.
Fun factoid: wealthy Teton County is the only county in Wyoming that routinely votes Democrat. Weren't Democrats once the party of the common man (and woman)? What happened to that?
