in the grand scheme of things it's not that important when the country is teetering on the edge of disaster.
Well, in the really grand scheme of things, the country isn't teetering on the edge of disaster because it won't be as bad as the Black Death, or Mad Max, impact from a 3-mile-long meteorite causing mass-extinction on a global scale, or the Sun going red giant and swallowing the planet in a ball of incandescent plasma. So really we shouldn't complain too much, eh?
With regards to whatever the acceptable medium grand scheme of things is, Leavers on this thread have already explained that they are positively delighted at the prospect of food shortages, job losses, businesses and skilled workers leaving, lack of medicines, and economic downturn resulting in less funding available for actually running the country. So not much to complain about there either.
Meanwhile, in the less grand scheme of things, we can express disgusted astonishment at people who value education, travel, and (rather importantly in many fields of work) the ability to gain wide-ranging experience by working abroad.
These things are not mutually exclusive.
