> Sometimes organizations improve because they want to
or that there's an alternative reason for their action other than maximal profit.
There's darwinian natural selection at work in the private sector (where reproduction can be taken to mean profit). Such a force doesn't exist in gov't funded entities providing a service. That doesn't mean there's no force to make those services improve - it's just not the darwinian natural selection force (may be a politician decides to make it his/her objective to improve XYZ as a promise for votes).
As for "no reason to improve" well, there's no reason for people to do more than the very bare minimum, and yet they do it all the time. Sometimes organizations improve because they want to. I might even argue that it's harder to improve under existential crisis, not easier.
I think it's become a bit of truism that private businesses are more efficient than government run organizations. I wonder if that holds up under scrutiny?
