I'm not saying that the conventional medicine is far from any criticism, but one has first to understand the difference between the current knowledge available, and the way it is used : some drugs/treatments are promoted by some countries, while not in others. I'm also convinced he drugs prices (which are going crazy) should be regulated for the benefit of everyone. And of course, modern medicine should be used wisely. People should not take drugs each time they have a cold.
That being said, of course, there are still room for improvement, there are a load of illnesses that cannot be cured by modern medicine, and yes, some doctors think themselves as Gods. But this should not question the many successes of conventional medicine.
