This forum isn't nearly as active as the psychology forum, just as a heads up.
I can't speak to SW as a social worker, but as someone who worked closely with LCSWs, the more lucrative route may be to get into administration or clinical director positions if working in agencies, which will take several years to climb the ladder. You could work toward becoming the head SW at an agency and supervise other SWs.
I also know an LCSW who is building a private practice providing individual/couples/family therapy. If you work enough years counseling folks and build up enough of a reputation, you could make that salary, but it will take several years to get there because if you take insurance, you won't be reimbursed enough to make that salary unless you also have a lot of clients paying full fee out of pocket (depends on how affluent your city/area is). As someone starting out in private practice, I'd estimate that it'd take at least 5-10 years to make that salary, and that assumes you have a specialty/specialized training or niche that will get clients into the door.
Hope that helps!
