That's the whole point. Employers don't want you to know about the real numbers. They want to pay you as little as possible. Even your manager doesn't make that much money. So they don't want their direct reports to have a higher salary. If you've ever asked for a raise you clearly see signs that they're trying to manage a budget.

Agreed with above. Salaries vary greatly by area. A dev in a non silicon valley type area could make 60% or less of these values. These look like inflated high cost area salaries. NYC, San Fran, Silicon Valley type areas.
