A Washington Post article about young people who work well-paying jobs so they can give much of their income away. For example:
Take Jeff Kaufman. A Cambridge, Mass.-based developer at Google, Kaufman and his wife, Julia Wise, managed to live on $10,000 in 2012, they say. Together, they give away at least 45 percent of their income each year (the rest goes to savings and taxes). Kaufman and Wise meticulously document their spending on their blogs. In 2010, for example, they spent a measly $164.44 on groceries each month and gave themselves $38 apiece to spend each week on nonessentials (including all non-grocery meals). In 2012, they moved in with Jeff’s family, which saved even more money, they say.
