Yellow is fake gold; it's veneer and show rather than substance. We see that with the yellow cocktail music at Gatsby's party (1) and the two girls in twin yellow dresses who aren't as alluring as the golden Jordan (3.15).
I think a moderate income is income above the median for famlies in your county, but not more than 25% of the median income. The IRS usually has this info for free, but I see they are now charging $10 for this on their web site for more recent years. http://www.irs.gov/taxstats/indtaxst...=96947,00.html.
1 Those whose incomes fall in the bottom 20% are considered poor. 2  Everyone else (the middle 60%) is middle class. 3  Income Range: There are some economists who say that anyone who makes between $25,000 and $100,000 a year is middle class.4  That might be surprising to some, though. For many tax policies, the cutoff often discussed is $250,000 (even though the fiscal cliff deal used $400,000 as the point for higher taxes), suggesting that some think that you can be considered to have a middle class income as long as you make less than $250,000 a year.
