True for wealthy countries, but in really poor countries access to things like medical care or legal services isn't a policy issue, there is a legitimate scarcity.

So we're not dealing in a world of perfect solutions, just less bad solutions, which is fine. Note that I'm speaking generally, not about the particular service this article is about.
