Slicing and dicing the body of American workers has come up with a new demographic: the "high-net-worker," with a high income and spending habits to match, an apparently inexhaustible appetite for work and scorn for the very idea of retirement.

These HNWs, according to EverBank research, are between 41–63 years old. They have an average household income of $374,000 and median investable assets between $750,000 to $1 million.

Those high salaries come with beaucoup hours at the office, and most of this HNW crowd puts in at least 50 a week. Notwithstanding, they have no interest in retiring as the magic age approaches. In fact, one out of eight (13 percent) never plans to retire. And the higher their net worth, the less they plan to leave the workplace. Among HNWs with household incomes greater than $500,000 and at least $2.5 million in investable assets, that 13 percent rises to 23 percent.
