* N'ont pas besoin d'être "rentables" (ie. personne ne s'étonne que cela ne rapporte rien = dépenses, investissements):
- armée
- police
- aide aux entreprises (CICE, baisses de charges, etc.)
- frais du gouvernement, présidence, parlement, etc.
=> Ce qui consolide le pouvoir.

* Doivent être "rentables" (ie. sont déconstruites si elles coûtent plus qu'elles ne rapportent = "trou", déficit, dette)
- retraites
- santé
- éducation
=> Ce qui crèe du lien social, du bien-être, de la solidarité.

@jz Army is a difficult problem which essentially comes to "If you don't maintain an army, you will be conquered (in modern age: economically bullied) by someone who does"

The "need" for most police and terrorism spending, that is highly questionable.

Aid to businesses, this one is little more than simple corruption.

@cjd well, France is "investing" in its army (to "not be conquered"(?) ), without approbation of its ridiculous parliaments, in: Mali, Mauritania, Niger, Libya, Afghanistan, Syria(?), Irak(?)... where else?

@jz Now we enter the wonderful land of geopolitics. In theory France might be extracting value from these countries which ends up in the pockets of the French. Ethical? No. But to stop means people will be in the streets. No nice answers :(

@cjd @jz Why does stop mean people will be in the streets?
