I think that's the key. Since the name implies they already HAVE a wage, a site with this name would be best utilized with tips/keys to 'optimizing' people's work habits, time management, social inter-office skills, profexxional input - in short, any angle that will improve their overall skill, desirability within the job, value to employers.
'Raise' may be the most apropos word here, but wagelift.com or wagelifters.com would also do nicely, they're available, as are wagefind.com and wageseek.com. wageless.com is also avail!!, so any of these last 3 could be a 'sister' site for those who need to get a job/wage in the first place.
