Today we have non scientists giving opinions based upon emotional persuasions and actions taken based upon that. To be sure there are always certain experts that will say things based upon their political persuasions. Consider though factories in China are re-opening as if the worst is over and if it is the whole thing was hardly an epidemic.
Many say China hid data; on the other hand if it wasn't such a big deal why would they broadcast it? The biggest proponent of the "end is here" theories is the media and, as shown by recent times' the media makes things up as it goes along. Mainstream media is on a downward spiral for many reasons but a big one is many are simply tired of the over political slanted reporting presented by them.
Regarding JB if he was really concerned he wouldn't be hawking his tax hike especially at this time but, like all Illinois Democrats, tax and spend is their line while lining their pockets.
