There are of course a lot of things doable fully in English. But when running a company not mastering the native language (even when all of the people you talk to speak English!) can be a big drawback.
"Trickle down" in the US is a term used to disparage the idea that a strong economy benefits the poor even in the absence of explicit redistribution.
[0] admittedly she was starting to develop signs of Alzheimer’s at the point she called it that around me, but that was a legitimate use of the phrase when she was young.
I still remember hearing two Dutch guys speak in Dutch, I thought there were speaking in English but then I realised I dont understand what they are saying.
It should not be too surprising, given that Scots in large part derived from Northumbrian Old English, with various admixtures including from Scandinavia.
The versions of English spoken in Northern England also had a large input from Norse due to the Dane Law period, and that is part of what drove the change to modern English.
That said, in viewing un-dubbed (but subtitled) Dutch, Belgium, and Swedish TV programs, I have been surprised by the amount I get the gist of directly from the speech. Generally from the core Germanic portion of the languages. Belgium was also interesting due to the occasional mix of stock French phrases and words.
There were a non trivial quantity of 'English' words used, and usually for identical meaning, or a similar gloss.
So 1.5m out of 5.1m, which works out as 29%. I'd suggest these being folk who learnt it as their 'mother' tongue, since Scots is not taught as such in the school system.
I'm not sure how that and the 1.1% figure for use at home can be reconciled.
So if we take that 29% figure, despite being a minority, it is still in a better overall position than Gaelic.
One would expect that Scots could be fairly easily saved from extinction if it got official support, but there seems little political will within the Scottish establishment (Parliament and Government) to do so.
This means the significant other has to find a job and fit it, kids have to go to school.
While many countries have a very decent proficiency in English, you're whole family must fully invest in learning the local language. And that in addition to using English in the office of at least one of the adults (since many big companies use English officially)
Like e.g. Berlin, the large Dutch cities are very much internationally-oriented and usually it's not problem to get a job and integrate if you don't speak Dutch. Sometimes the issue is quite the opposite -- my wife wanted to learn Dutch, but people would just switch to English or German and she would have to ask them explicitly to speak Dutch.
This means the significant other has to find a job and fit it, kids have to go to school.
Kids pick up other languages in no time. A lot of friends/colleagues moved between countries (academia) and the kids would usually pick up a language in 2-3 months. I have lived in Australia for six months when I was four. When we returned, I spoke English with an aussie accent (though that's gone now ;)).
Some people can deal with this, even long term, but it's definitely not for me.
