I don't think we have an obligation to legislate everyone's health, but I do think it's a higher ask when we're talking about explicitly subsidizing bad choices for people most vulnerable to making them. I don't think we should subsidize cigarettes for poor people, either, even if that means they are still accessible to rich people in a way that's perceived as unfair.

And besides: people of high incomes already disproportionately avoid these highly processed foods, so it's not like we're hoarding the wealthy pleasures of Mountain Dew and Twinkies just for them.
