> We should find out why the poor have worse dental outcomes and address the root problem
The root problem is that parents that are absent, either for noble reasons (working multiple low-wage jobs) or less noble reasons (addiction, abandonment) will not have the presence to enforce good dental hygiene.
There will always be some subset of parents that are more or less absent, and the main solution that exists for that in the US currently i.e. the foster care system has measurably terrible outcomes, and so it is only applied in the most egregious cases.
Why should we let perfect be the enemy of good here? I'm all for removing fluoride from the water, once it has no benefit on the population. But currently, it has a huge benefit, just on people who are least likely to advocate for it.
"You're just pushing your "Benevolent But Superior Intelligence" onto people" is an appeal to emotion, not a solution to real problems that real children face.
More emotionally: it's fucking embarrassing we let bullshit arguments like this hurt people in real life.
