Perhaps because we only spend money in cases of emergency. That is why we have emergency money and emergency supplies and food.

Health care, yes treat the trauma, because it does not make sense to treat a healthy person for an illness they don't have. Yet I agree we should spend money to prevent the illness in the first place, and that would save money from having to treat it for a lifetime which would cost more.

I suppose it is like putting out a fire, it costs a lot of money to put out a big fire, but the amount of money you spend to try and prevent it would be a lot less than it takes to put it out.
