There are countries where it is common to hire without having wage negotiations. Look at all Russian IT job sites: more than half of all job posts look like "senior computer programmer - $2000k ± $10 per month", and there will be few job posts with 3000 and higher montly wages, but the application counter for each of them will go from few hundreds to 65535
Russians don't like to bargain mostly. I suspect (but please correct me if this sounds too wrong/offensive), that it's a vestige of the planned economy they had - all salaries and prices set by the state, no bargaining allowed. It's a simpler system and removes not only a layer of stress, but also a layer of conflict between you and the employer.
Though, if I were offered $2000k/mo, I wouldn't feel the need to bargain at all ;)
I lived for a while in a post-Soviet country, and bargaining was a regular part of every day. At the bazaar, in private cabs, even at black-market money changers if you were brave/stupid enough to use them.
My brother-in-law is Russian, too, and I've seen him haggle over cars, electronics, home appliances, any "major" purchase.
Not sure about the US, but here in socialist Europe, that's pretty much how the entire public sector works. You have very fixed salary-steps, based on education, job function and seniority and there is little to no room for negotiation.
