When I went to malls as a teenager I would often get stopped and searched as if I was shoplifting. Was over 6’ at 16 and often wore hoodies. When I started getting into cross-dressing I was too ashamed to go through checkout with it. So I dressed in nicer clothes then hoodie and jeans, and shoplifted women’s clothing from every clothing store that ever stopped and searched me incorrectly previously. Part shame part revenge part kink.

Spending and consumning less could help more. Espicially gas and meat.

Rate could mean over time or percentage of. I think OP was thinking of time, in which case your wouldn’t need the total number of schoolchildren. Just divide the population of billionaires by the number of schoolchildren that die by violent crime per year.
