If you have a friend, and you say you do, that became a doctor ask him or her how much it cost how much it cost to get through college, medical school, internship and residency. (Would you like to post it here?) That's 10 years of education after finishing high school without any speciality training even.
After which those newly minted medical doctors (M.D.) are going to stick to the medical books (their dogma) on which they just spend enourmous amounts of time, money and frustration to learn. And charge as much as the market will bear to make up for it, and to pay back the loans as fast as possible. So they can live the fast life, high life, living large, plush, high end or however you categorize being rich. To be doctor is not for the poor or middle class having trouble making ends meet. That story belongs in fantasyland to be enjoyed once in a while but not recomended as a real option.
