It most certainly can't, no country's economy can withstand a prolonged lock-down, and by prolonged I mean just a couple of months. I saw recently that the US alone was expecting losses of $350Bn by the end of March , and that is with only medium measures in place. And failing economies isn't just a problem for people pouring over stock market screens, or waving bits of paper around. Its problems for ordinary people being unable to work, to pay their ways, to look after their families. And when that happens civil unrest is inevitable, and the consequences will be far more devastating & far more reaching that Covid-19 could ever be. We've already seen the panic when the supermarkets are open and people still have money. Imagine what would happen if the supply chain did start to falter, and people started to run out of money because we kept in a lock-down on for too long. It doesn't even bear thinking about.
