...not only those groups but younger healthy people will be at a greater risk of getting hospitalized from the virus as the amount/dosage/concentration of the virus contracted will/may have a dire impact on you, especially since our individual immune systems react differently, especially if we're stressed and tired. That's why otherwise young and healthy healthcare workers around the world are dying like flies.
If we didn't have these lock-downs and shelter-in-place policies, we would be "bombarded"/saturated with the virus due to its specific nature (like the extremely long incubation period and the virus's ability to stay "alive" for up to 24-72 hours on certain surfaces), so not only would the old and already vulnerable portions of the population die fast as you and I too would run a greater risk of running into severe COVID-19 related complications. I have one friend in NY who just recovered from the virus. She said it was several times worse than the worst flu. She gets winded super easily now and gets breathing pains if she overexerts herself the slightest. She's not even 40 yet. She is worried that she has permanent lung damage to her lungs now.
Sure, the country and the economy needs to open up at some point, and preferably sooner rather than later, but it needs to be thoroughly planned and and with great caution, carefully calculated/guided by actual experts. A more or less improvised state-by-state basis opening of the economy is most likely going backfire with a resurgence a bunch of weeks from now, even with prolonged social distancing and people wearing masks.
With that said, those armed Tea Partiers and Confederate flag waving so called "patriots" protesting in the streets, defying social distancing while not wearing masks, need to be dealt with and escorted home as they are definitely potential so called "super spreaders". Imagine if these protesters had not been whites but blacks, latinos or Muslims? The tone and response would've been quite different to say the least.
Another scary fact is that the current administration has not even thought about who would be liable if/when employees contract the virus and suffer from the consequences... Who's gonna pay for the medical bill? Will the employer/company be liable for exposing their employees to the virus? Or will the federal government step in and cover, or will they dump it on the state? Or even worse - will it be up to each individual to pay for the tens of thousands of dollars it will cost for treatment, a hospital bed etc.?
