They are responding to a factual statement: "... caused widespread misery in Europe".
I live in Europe and have to laugh at that. The misery they're talking about is a 2x increase in the electric bill, which some of the richer governments (e.g. Sweden) paid back to most consumers (I got two paybacks so far, making my electric bill for the year about the same as the year before, I would say). If they think this is "misery", I think the commenter has absolutely never seen anything even close to real misery.
