I doubt that the government will suddenly say 'As from tomorrow, everything back to normal'. I think regulations will be relaxed gradually, perhaps some area before others, sometimes with them being reimposed, so I think the mad rush of travel is likely to be filtered in.
Yes, for those on limited income during this time of hardship, things will be difficult, but do not forget that there are millions of people working from home doing there job as before and being paid as normal, plus, of course all those who have continued to work outside the home during the pandemic from NHS staff to home delivery people.
Many will have made savings during this time because they have no travel expenses, are not eating out, going shopping, as a leisure activity, going to sports stadiums, cinemas, theatres. etc.
These people will be rushing out to eat out, mingle with other people, go to museums, sports events. These are the kind of industries that employ those who are now out of work. I think thebleisure industry will boom.
Yes, there will be casualties and there will be problems, but not as many as some miseries seem to hope.
