You might want to check the data. 92% of covid deaths are 55 years and older. Seems to me the younger generation can open up safely with proper precautions.Because we don't know who has the virus. Remember you can be asymptomatic and spread the virus. Young people are dying from the virus and having side effects that will last a lifetime. This virus is not like anything we have every seen. The governments make their decisions based on medical evidence not the stock market or your bank account. I agree take it slow and see what happens. If you opened the country and your wrong the country would plunge into a depression and the worse medical disaster in US history.
It would be interesting to see if one country opened up and what happened to their citizens. The country would have to be totally quarantined from the rest of the world. You have a 50/50 chance everyone survives it.
