The only way a sane person would reopen the US economy is by employing:
Only people who test positive for the antibody, plus...
Of the remaining population, only people under the age of 40 who live away from people over 40, and who have tested negative for the virus. Plus they need to implement a cellular boundary format so that worker communities stay within their own cellular area and don't carry the virus to other communities.
They need massively to crank up the testing regimen before they do anything rash to restart the economy.
