> I'm not being flippant here.
Sorry to say, (Canadian here), yes you came off as being flippant. The issues with Flint seem to be larger than my understanding, but it was not the least contributed by issues and injustices with the demographic (majority black) and the lack of federal aid. Saying it's not a first world country isn't wise of you for these reasons and more.
> Then the best solution is to keep paying for bottled water, or to move.
Obviously not the best solution, just a bandaid over the problem in lieu of the fact that "Bottled water is 3,500 times worse for the environment than tap water".
> you can't trust the country where you live to provide you with access to clean drinking water, then you have literally failed
No. The government around the citizen failed. Saying the the victim failed is quite telling of your assumption that the individual is to blame if the government has in some capacity, in some municipal area, failed.
> literally failed the UN's Sustainable Development Goal no. 6
The goal is tied to a future date, you cannot fail it by definition in 2021. I'm sorry to say, and I'm also not being flippant here, basic math and logic is taught in "first world countries", your comment here is obviously a failure of such, and I'm sure, there's probally a UN goal I could quote as well. See what I did?
