I don't see people dying to get out of America. But there are plenty dying to get in, so perhaps there's something America has that outweighs whatever you think is going on.
By the way, you probably think far more people are killed by "assault rifles" than really are, judging by your hyperbole. In 2019[1], there were...364. By contrast, there were 328 million people in the US in 2019[2]. That means 0.000001% of the population, which, while tragic, is statistically insignificant.
