Everyone knows what lightning is, when it forms, what to do about it (go inside), and why it's dangerous. Yet still, somehow, people get struck by lightning. It's not like this knowledge is new or controversial, so why is this still a problem?

Does this clarify things a bit? I'd like to find a better rhetorical method than just swapping out terms, but it really does highlight the point here. Can we conclude that government is trying to kill people just because some people still get struck by lightning? Alternatively, what would the government need to do to prevent anyone from ever getting struck? Now consider all the different ways people can end up poor, and project this infrastructure out to ensuring that that can never, ever happen. Should we have better methods to handle it when it does? Probably! Does the fact that poverty traps exist mean that people explicitly set them up? Probably not!
