The only difference between the North American carriers and the overseas ones is that they sprung for the option that tells them that the MCAS is about to point the nose at the ground hard by displaying a warning in relatively small writing on a screen somewhere near the middle. Apart from that, which may not have made much difference there is no overall difference in terms of safety or training that would have prevented the Ethiopian crash. Ethiopian is a state-of-the-art operation with a modern fleet. Lion Air is a bit more questionable, but their 737 crash appears to have nothing specific to that airline or being based in Indonesia. You may have other evidence of hazards, so might I. But the 737 MAX saga isn’t it.
