In Holland some people are changing their minds after 2 weeks of lock down and believe the economic costs are worse than the virus. These people do not understand exponential growth.

Nor do they understand human psychology: if people start getting extremely sick left and right they will panic, which will be even worse economically than a temporary lock down in which most people still trust a government

Only with ubiquitous tests and with everyone wearing face masks after a lock down you can contain it.
