We're all familiar with the 80-20 rule, correct? How about the 1-20 rule? I read this morning that US wage earners in the top 1% (which is those earning about $325,000+ per year) take up about 20% of all total earning in a year. That is a bit staggering. I am sure that many of those folks are very, very generous. But, I wonder, if you break down wage earners into certain wage range categories, which category would be the most generous in terms of the percent of their income that they give away?
