You still need the money to go on holiday in the first place and the OPs point was that working people in the UK can't afford to go on holiday.
There are working people who will just get laid off, because they have been hired to - let's say - coordinate a "shared service center" enlargement, but now that won't happen, because the company will instead freeze every expansive project in the UK due to the suddenly increased uncertainty, and that guy (gal) will probably won't go on holiday, though he (she) will have a lot of free time to like the holiday posts of others on Facebook.
