How does the government of France decide whether your kidnapping is worth sending military tactical teams to rescue you?
In any case, if there is any sort of kidnapping or hostage taking they send the tactical units.
To foreigners, GIGN is perhaps best known for being one of the counter-terrorist teams in the Counter Strike game.
Here's an example of an intervention, a video where they shoot in a guy's leg (long distance, with a submachine gun...), to prevent him from shooting himself:
It's not a political "cap on how much to spend on saving somebody's life". There have of course been rescue operations more expensive than that per person, and some medical expenditures exceed that cap as well.
And in the US, these drugs are much more expensive.
In many countries, including those with both socialized and private healthcare, insurance companies routinely pay for treatments costing much more than the statistical value of life.
Also, these incredibly expensive single-dose cures usually are that expensive because they don't benefit from any economies of scale and/or haven't recouped their investment yet. In competent healthcare systems, the price is driven down substantially sooner rather than later for almost all drugs through negotiations.
