Cost of living is just one variable when accumulating the data used to make this decision. To go squarely by COL would be inaccurate since most people live beyond their means anyways. If you used COL only, almost everybody in an area would be considered poor.
To go squarely by average income for an area wouldn't be right either but it does paint a more accurate picture. To compare our profession to janitors and brain surgeons isn't apples to apples either but when you compare our competitors wages to the average income, you'll find we're not that far off.
Even when you compare $23.68 to $25.08, we're only talking $3K a year BEFORE taxes...is it really that much to complain about?
Most people **** away 3K a year buying crap they don't need, with money they don't have, to impress people they don't know!
