I would call it a directed question, as I'm not sure the UK is struggling more than any other country.
The whole western world offers less for the future than it did in the past.
Less free education, less free health care, less pensions, less chance of staying married, less chance of home ownership, less job security, longer working hours and years, more homelessness.
But of course the whole thread is designed around slamming Brexit, so the rest of the world was deliberately left out of the question.
