I've lived and paid taxes in three of the G7 countries, including the US.
For what it's worth, I've had to fill out tax assessment forms of greater-or-lesser complexity in all of them. The US is certainly the worst, but the trope that "all other major economies just take care of the tax for you" isn't exactly right.
So long as you're equally critical of all statements that "aren't exactly right" even when they come from groups that advocate for your political preferences, this is a totally fine and reasonable comment.
My comment is totally fine and reasonable because it's based on me sharing my personal experiences with others on HN, who may not have similar experience. The insinuation that this somehow comes from a viewpoint of political bias in uncalled for.
