Problem is they want senior developers but only want to pay junior developer wages. There is a flood of junior developers out there that can't get jobs. These companies don't want them though. They want senior developers who don't have to work for those lower wages because they can easily make $170k on their own or elsewhere. If they really do want those senior developers then they need to pay up. Otherwise, hire junior developers and put in place a program to get them up to speed.
