People being made redundant, will obviously help an effect. Is that right, ymb, that over a certain limit, you get less than 80%? And presumably, those are businesses that should be able to afford that.
For those on 80%, it will be enough to close some businesses, but many restaurants, cafes etc are doing deliveries, takeaways etc.
The redundancies are probably the biggest problem. And also for those self-employed who haven't been entirely honest.... if you have been pretending you earn a lot less than you did... you will lose out, as you haven't paid enough taxes or shown enough profit.
