A lot of these posts are assuming two things: childhood trauma is more prevalent in single parent households and households living in poverty. Both might be true. Here's a small sample sized study supporting that notion:

But 71% of children live in two-parent households and 84% are living above the poverty line. I think we, as a society--and maybe through govt policy--should help kids living in poverty or more likely to see abuse or trauma. But to defeat are greatly reduce the childhood trauma in the US, we might get more bang for our buck by changing attitudes/actions/parenting in the situations we find most children.
Here's the first paragraph of the article linked in the OP:
Twenty-five years ago a study by the US Centers for Disease Control and Prevention (CDC) revealed that, in the United States, traumatic life experiences during childhood and adolescence are far more common than was expected. The participants in that study were mostly white, middle-class, well-educated, and in possession of good medical insurance, and yet, only one-third of them reported no serious adverse childhood experiences. In the remaining sample, the vast majority had experienced two or more horrendous childhood events. Subsequent scientific reports from 96 countries have shown that, globally, over half of all children – one billion girls and boys – are exposed to violence each year.
