The common procedure of invasive cardiac intervention and intravenous magnesium administration before reperfusion should without question become the gold standard in treatment of acute myocardial infarction.  Two meta-analyses studied the impact of magnesium treatment on reduction of the death rate and rhythm disorders in the acute phase of myocardial infarction before initiation of reperfusion treatments. Both reports found a 54% reduction of the death rate, and one noted a decreased incidence (49% less) of ventricular fibrillation or tachycardia in the population treated by magnesium.  The most important action of MgSO4 in AMI is to open up collateral circulation and relieve ischaemia thus reducing infarct size and mortality rates. 
The degree of antagonism is not just driven by personal opinions about education levels, but rather by antagonism that has been delivered toward nurses and other providers by physicians. I was an RN before I became an NP, and the only provider to ever throw a hard-copy chart at me because I refused to write his orders like some little scribe was a physician. The only provider to ever openly ridicule me because he disagreed with my GCS calculation (by one point) was a physician. The only provider to ever write petty retaliatory orders because he was ticked at me for not joining his entourage was a physician (infuse 100 ml of 5% albumin over 12 hours). A FELLOW refused to allow for the overnight extubation of a post-op patient because she didn’t like the marginal lactate level. When I shared the general sentiment of the attending surgeon was that this patient should be extubated by morning rounds and that the scene would be ugly if we didn’t at least try, she pushed back. She had the benefit, however, of being somewhere else when the physician talked to ME like I was a three year old during morning rounds, meticulously explaining to me with dripping condescension how to wean a patient for a successful extubation, as if I was the obstacle to the overnight extubation. Deal with that nonsense for a few years and then maybe you’ll understand a little residual antagonism.
Finally, as a Jew, I am loathe to dare to judge the Germans of 1933-1939. How can I know what it was like to live under insidious propaganda from the radio and the press, day in and day out, with Nazi ideology creeping into all walks of life. Listening to the BBC was forbidden, the feared Gestapo was everywhere, there was a virtual state of emergency and rule by fiat almost from the beginning of 1934 and the noose tightened ever so slowly and by the time anyone knew what really was about to happen, it was far far too late to protest. Remember that the final solution only became offical policy after Wannsee in 1941. Until then, German policy was merely to make Germany 'Judenrein', free of Jews. The average German acquiesced, some happily, some reluctantly, and some protested, but every newspaper, radio broadcast and official spouted that the Jews were the cause of Germany's misfortune, Get the Jews out of Germany and Germany would become great again, and that was what people believed. They simply believed that the State knew what it was doing. Remember too, that nobody could get a job unless they were members of the Nazi party.
