Taking businesses off furlough is also going to create substantial problems. e.g any retail business that goes back to work is going to have the same tight margins and high expenses that they had before the pandemic, but now with vastly reduced customer base. Similar problems in manufacturing. Far fewer orders, far less activity. It's not as simple as 'lift lockdown, get back to normal'. Even if, as I just have, you totally ignore the risks associated with further outbreaks. What it would probably take is a carefully planned exit from lockdown (track, trace, regional response), combined with a major economic stimulus package. These things are possible, they've been done before, but the Tories are fundamentally ideologically opposed to them.
