It was a few hundred years ago that Benjamin Franklin made the observation that time is money. The same is still true today, and workers are constantly trying to strike the right work/life balance to get as much as they can of both.
According to the 2008 American Time Use Survey (conducted by the Bureau of Labor Statistics), we're still working an average of eight hours a day. And the most recent figures from the U.S. Census Bureau indicate that the median annual income per household member is $26,036 per year.
There are some jobs, however, where you can work less and make more than the averages. The hours may not be significantly less -- generally between 35 and 38 hours a week -- but these jobs offer more value in both time and money. They all pay salaries that exceed that $26,036 median income.
