Chill buddy. You worry too much at your stage. I still believe that there are rural and semi-rural areas with fewer Corps. I was in Alaska last summer. Visited some small towns. No Corps there. Fact ... the nice, urban, coastal areas are saturated. These areas are also populated by the low income set. Most Corps (ours does) market to the lower income patients. You want the dentist dream? It still exists in the smaller, less populated, less desirable areas. You may or may not make as much money ..... but you have the opportunity to practice dentistry as YOU WANT.
I'll say it again. Corp is ok for an older dentist like myself, but not for young dentists with DS debt. Corp is a dead-end for young dentists. You still have time. But how long? Who knows. Start or buy that private practice in a rural area while you still have that opportunity.
btw: if you practice in a small rural area .... sell that Lambo (your avatar) with the scissor doors. It won't go well in a small town.
