Why is Birth a "For Profit" Event?

Even though healthcare in Canada is not "For Profit" (as in the US), many of the same mindsets appear here. I do not understand---other than greed---how a country has let birth become a money making event.
One area of profit for hospitals is epidurals/pain relief. There was a great blog post yesterday about this: http://wonderfullymadebelliesandbabies.blogspot.com/ Look at October 7 (I can't get it to make a simple link to the actual post). Doctors getting plasma TVs for having the most number of medicated births in a hospital?

I think it would be a great idea if doctors, especially OBs, and hospitals had to make these things public. You know how books give you a list of questions to ask your doctor....what about "What sort of bonus do you receive from XYZ drug company" or "What have you received in the past 6 months from Similac?" Even better would be a doctor-disclosure pamphlet which details c-section/VBAC/vag breech/epidural/pre-date induction rates, with costs, income, and bonuses clearly stated.

The saddest thing is that birth outcomes in the US do not indicate that 'for profit' birth is better than non-profit birthing countries.
