A single cent? I think you vastly underestimate how little a dollar does in the US, and how much it does outside.
Moreover, insisting on going all-in on medical research before doing any immediate lifesaving sounds to me like a gross perversion of what should be, in its most simple case, an urging to make sure your kids are clothed and fed before donating to the food bank. Surely ordo does not make it unvirtuous to save a drowning foreigner even if your kids would miss a meal for it.
I’m under the impression that Aquinas says outright that it makes sense to make exceptions to the general ordering to aid those in grave need that are “low” in the order, and stuff like mosquito nets are a prototypical example of this imo. Lives saved, families preserved, terribly unjust suffering averted, etc for literal pennies on the dollar.
