There are reasons that the number of medical school applications far outnumber the available positions.

And I don't think that the ability to incorporate ranks very high, if at all.

For every person who decides not to practice medicine because of changes to tax law, there will be ten more hoping to take their spot.  (At UofT, over 3,000 applications for 259 spots.)

I don't personally agree with all the proposed tax changes, but I am tired of hearing doctors complain about this, as if  there were no other reasons to practice medicine.

Even before doctors were allowed to incorporate, it was a great job. True, you might not make as much money as some people in business, or even as much as some nurses (once you include all their benefits), but if that's what you want, go into business or nursing. Otherwise, medicine provides a comfortable, flexible lifestyle with little fear of unemployment.

There will always be other people lined up hoping to take your spot at medical school.
