It completely does. Why are cloth diapers third world? Why are disposables seen as so superior that they should be had at a discount? They should be expensive to account for their environmental cost. Just because they didn't care about that in the 50s doesn't mean anything.
Cloth being better is something else entirely, nor was I suggesting that disposable diapers be discounted with taxpayer money. The point was "Why does the poor in the richest country in the world have to worry about something as inane as affording diapers in 2018?"
I agree that people should use cloth - but the response to "Hey, this poor person can't even really afford to buy diapers!" shouldn't be "wow that damn government making her dependent on welfare bux, shes so dumb she doesn't even know about cloth too!". It just reeks of being completely out of touch with the poor experience in America. Maternity leave isn't really a thing for someone like her - should she maybe be working an extra job or two to afford better diapers? Even if she doesn't, how do you know she has the time to deal with changing and washing cloth diapers? Being a stay at home mom doesn't exactly work as well as it did in the 50s or 60s, and she doesn't have a husband working for a tech company or whatever who can support a family on a single salary.
Let's be clear and honest about this article: there was no second job for her to work because she quit her first job before the baby was even born to go on assistance. Your argument doesn't hold water with me. My mom worked when she was pregnant with me and went right back to work after I was born. My wife, a physical therapist with a physically demanding job, worked until the very day both of our sons were born and then went back to work four weeks later. The girl in this story did none of that. Again, I don't blame her--the system practically invited her to do this.
The discussion was about how something that almost every parent uses, relating to one of the most basic human functions, could be outside of the purchasing power of an inhabitant of a major developed country.
I don't disagree with a discussion on how we externalize costs in cell phones, take out food containers, packaging for toilet paper, or whatever else. But however reasonable that discussion is, it was besides the point of this discussion.
So yeah, it's incredibly relevant.
