Point well taken. Consider though that New York City was supposedly "locked down" and still is but maybe the largest disease spreader/multiplier there is (the subways) continued to operate 24/7. Now they finally realized hey maybe we need to shut them down for a while every day to clean them. It is also true that the horrible decisions in those "lockdown" states led to a large percentage of their deaths.HHS Secretary Alex Azar said today that "actions to delay and flatten the curve have saved hundreds of thousands of lives that otherwise could have been lost."
See 10:45 mark
So if lockdowns were ineffective and counter-productive, why does the HHS secretary think they saved hundreds of thousands of lives?
The population concentration, modes of transportation, number of people who carried the virus in, etc all contributed to how many cases those states had. Clearly Pelosi, DeBlazio, Cuomo etal who were still encouraging people to head to Chinatown and ride public transportation in to March had HUGE part in their problem. It's one of the reasons I get so pissed when I hear them all blame others for their failures.
The good news for them is that they may be approaching rapidly a large enough population immunity in those hard hit areas to really whack new infections. One other factor IMO besides the living conditions in their poor neighborhoods is the vast number of people in cold climate urban settings who are Vitamin D deficient which has proven to be a bad thing when infected.
Personally as scared shitless as those states are they could probably open back up with a mask policy and be just fine.
