I know HN is very leftist, so I expect downvotes. It'd be nice to have a discussion though.
So "Europe" is maybe a broad term here.
Would love to hear about systematic issues in Sweden, Germany, Norway, France, Belgium, Switzerland etc. All have strong government role in regulation and municipal water supplies.
Your comment implying political bias for everyone who disagrees with you is cheap rhetoric. And, the US is so far right on the political spectrum that anyone “leftist” there is likely to the right of the center in the EU.
All you have shown is that Czech government needs to improve.
Edit: And it certainly isn't comparable to having water that's not safe to drink at all (bad water being the rule, rather than the exception).
