Same reason the public transport never closed for the homeless in NYC. Political interest.
This whole lock down is done to control people, to destroy the economy and to implement socialist ideals on redistribution of wealth, government income etc
The largest vectors of disease in NYC and LA are not only allowed to roam the streets but hospitals have to accept them and provide housing for them.
Private hospitals are on the verge of collapse if not bankrupt already, because lockdown policy without reimbursement. This is the largest government takeover of health providers, private business and public policy in US history.
The only reason we've been able to respond better than both Europe and South Korea is being destroyed, better testing per capita, better death rates per capita, better infection rates per capita and the leftists government is pursuing policies that were in place in NYC - the only place in the world where the disease is the worst - because failed government and failed government healthcare facilities.
