The answer to the question with regards to the COVID-19 pandemic is, "not a damn thing!" Nothing has changed publicly in regards to the virus, any current treatment, immunization or proven new treatment or medication. So why is the world (and in particular the United States) beginning to open it's businesses for business as usual? Well again, that's easy, it's money and the acquisition of it. Instead of finding ways to sustain the masses without subjecting the populous to the spread and horrors of a disease that has yet to be contained we will put those, the most vulnerable at risk so the few, the least vulnerable can acquire and build their already obscene fortunes even more!
Nothing has changed yet folks! But let's not act responsibly nor even civilized. Let's be utter greedy bastards, which brings up and whole slew of issues about our society, cultures, religions and you name it!
