No, it doesn't. Saying that people lack an ability is not the same as claiming that the problem is a simple matter of instilling that ability.

It also isn't the same as shaming people or making a moral issue out of it.

> Or is that too scientific?

The snark is uncalled for. "Science" doesn't require ignoring obviously true proximate causes in search of ultimate causes.
