Politicians and health experts have juggled with the decision of when businesses should start opening up. Even when businesses begin opening up for good, it will still be months, maybe years, before the world goes back to normal.
Certain businesses need to wait for the next phase to reopen, such as schools and day care centers. This means parents can return to work without having anybody to watch their kids for them in the meantime.
The economy has to be careful to not open to soon, in result of an outbreak. But the longer the shutdown, the more permanent the damage will be.
