"In line" is a bit of a stretch, the median gross personal income for full time workers in the US is slightly below 4000 per month.

EDIT: The median personal income for all workers (including part-time), is of course much lower, more like 2700.

But it doesn't make that much sense to compare the national median income with a high CoL area, where you also expect higher salaries.
