At least those of you that are graduating have something to rely on if you do not land in a private practice. It's a job. That's it. I graduated in 1993 and guess what? No one was knocking on my door offering me a signing bonus, salary and benefits. There were no Corps then. I literally had to send emails, letters, hitting the pavement looking for a job. It wasn't easy. 1st situation right out of school ended miserably. I went and "shadowed" an older Orthodontist who had multiple practices and eventually bought one of his locations. I view it as buying myself a job.
To summarize: Corp jobs offer young dentists immediate income and a chance to work on their clinical skills. Once you've paid down a little debt and are clinically capable .... look for or start your OWN practice. You have the time and energy to do this. Do both if you need to until your practice is up to speed. Then when you get older ...like me .... Corp offers you another option. Teaching at dental schools is usually full time and you are paid less than Corp (I've been told). If you still want to earn decent money, work part time and have no management stress ..... Corps is there for you.
Those of you that want to blame Corps for all the problems in dentistry are short sighted. Technology combined with capitalism has made it difficult for EVERY job and profession through out history. That is inevitable progress .... for better or for worse.
