It's a sensationalistic story.
It's not a comprehensive study.
It's only the account of one boy.
It's certain there are other reasons why this happened.
But does any of that matter? The fact that it happened at all is bad enough.
Children should not be allowed to die of toothaches because they don't have insurance or money to cover simple dental care. This definitely should not be allowed to happen in the US of A. This is why relative poverty matters. This is why health care in this country needs urgent reform. And this is most definitely why healthcare reform in this country should account for the poorest in this country, even if they are fabulously wealthy by global and historical standards.
