Simply read letters to the editor or eavesdrop at your favorite restaurant around early bird special time, and you'll hear much talk about the difficulties of living on a "fixed-income." This is particularly bothersome to me because, even though I am not retired and still younger than 30, my income is also "fixed."

My income is not based on the phases of the moon, nor is it determined by luck or chance, nor is it a bottomless cash fountain from which I pluck a few dollars when I need them.

Other than a few exceptions, such as those in sales or other commission-based fields, it would seem most people are on a fixed income. Maybe those who use this phrase mean they are invested in the bond market? That's considered a fixed-income security, vs. the variable-return stock market.

Or maybe they mean to say "low income" or "without an abundance of disposable income," but they certainly don't mean to say "fixed income."
