DK I have a similar opinion, I expect another LD at the end of this year. It would seem reasonable to say they can't keep happening - but this is where UBI comes in to play.
I hope you're right, but only time will tell how effective the vax is. Also, some people will still not want to travel, some will remain working from home and many businesses may not reopen.
DM, You raise some valid points, but are 'we' (as a nation) now in a worse situation than a year ago. To what extent do lockdowns work and how effective is the vax. Where do governments go from here - do they want LDs to be permanent.
