There's a lot of hate for open offices, yet they're everywhere. There's high demand for developers, and accordingly, the salaries are high. Open offices mainly exist due to cost savings (lower sqft per employee), yet for most businesses salary costs will completely dwarf the cost of office space. Something doesn't add up.

Do places with open offices have a harder time finding people? I was trying to find some comparisons of average salary at places with open offices vs private spaces, but I can't come up with anything. Intuitively, I'd think the salaries would on average be higher at places with open offices, but perhaps that's not a consideration of most people.

How much more money would you need to be paid to make working in an open office worth it? Conversely, would you accept 5% less to get a private space? 10%?
