Yeah, I don't get this.
I was very skeptical of the lockdowns, but at the same time, to a large extent I don't think the government had much choice. Apart from Sweden, it seemed like it was the medical community consensus, the media was pushing it as that, the public was scared, and the opposition wanted them to go further.
And once they did it, they had to mitigate financially, or people would really have been in trouble.
I think people somehow believed the financial aspect would not come home to roost. It's the same in many other countries too - they are now feeling the effects and people who were for it seem to think it's somehow it should be "fixed".
I blame some of it on the idea, which seemed popular on the left for a while around the time the pandemic started, that they could just put more money in the economy, indefinitely, with no downsides. Funnily I haven't heard much about that lately.
