One could attempt to employ a "last grain of rice" cost-benefit-analysis strategy. Some could say it's biased for the nit-picking, but consider just one example -- IF -- IF -- you could detect it, collect data and do a statistical analysis.
Getting slapped in the face daily by Trump while watching the news COULD be considered a matter of choice, but if your habits don't differ between administrations, perhaps this is worth considering. Has it had an impact on your mental and physical health? Has it had such an impact on any number of citizens? If the answer is "yes", then it has also had an effect on life-spans. Or on medical expenses. (Would the health insurers be interested in that? Would they advise you NOT to watch TV?)
Of course, in addition to "body counts", you have the entire federal workforce thrown into total short-term financial insecurity when Trump pulled his stunt of attempting to extort congress over his border funding and leaving people to work without pay. Add to that the costs -- if you could identify them in dollars -- of trauma to kids separated from parents at the border -- some several thousand of them.
None of these lesser things -- exclusive to domestic life in the good ol' USA -- should be denied, since we're already looking at mass-shootings and other phenomena.
