>Even if you can find a job in English (which is possible, things like startups or video game developers are sometimes in English), you will need the local language to talk to shop keepers, repair men, salespeople, any government worker, etc. Basically all the day to day bullshit errands you need to do are only doable in the local language.

In Nordic countries at least, that is indeed not a problem. Literally everybody speaks english at some level, and the whole especially in the larger cities you can often end in shops or restaurants where the people that work there only speak english.
