This. Someone like this could maybe come up here to Canada, and enjoy slightly a more sane political/cultural climate, but they won't be getting this kind of funding. Academics here are already barely holding on, and even in the best of times there has never been the kind of flow of cash available in the US for scientists and intellectuals.

I imagine a similar story applies to the UK and other places in the Anglosphere

Unfortunately, very true. I think Canada ranks last in the G7 on GDP-percentage science funding. Salaries seem to be OKish, maybe similar to Germany, but cost of living (mainly housing, food is comparable cheap) in Vancouver and Toronto is very high.

UK salaries are atrociously bad. Not sure about funding, but it doesn't seem to be great.
