Did you even read through the website I linked above? Your references are badly outdated. While the AMA once lobbied Congress to limit Medicare funding for residency slots they reversed position years ago. And even back then, there was nothing stopping teaching hospitals from expanding residency programs using their own funds or other sources.
There are valid reasons to criticize the AMA but blocking the training of new physicians isn't one of them.
