The "if it saves even one life..." argument is invalid on its face. If that was justification for any of our public policies, we'd be driving at 15 mph on the highway, because doing so would save thousands of lives every year.
It's really pretty simple to break down, when you step into the world of the surreal, and attempt to think like a politician. There's two reasons for this. Here goes... a trip into the mind (first person) of a politician, like Whitmer... hey, this dictatorial power is awesome! Also, with the economy opening (even in sensible phases) any virus related deaths will be blamed on... me. Red alert, we can't have that! Alternatively, with the economy shut down and shelter in place orders in effect, virus related deaths will be blamed on the virus. Situation normal; alert level green.
Other types of deaths related to the shut down are absolutely insignificant to them.
They don't care about the increase in deaths related to people losing their livelihoods due to this un-Constitutional govt over-reach. They don't care about how that will impact other areas, such as people not being able to see their doctor for things like cancer screenings, and other types of serious diseases. They don't care about increases in depression, alcoholism, spousal abuse, etc., etc., etc.
They will tell you that you're selfish if you want to let people provide for their families, which to most of us is pretty darn essential.
They only care about maintaining their power, and not being blamed for any deaths.
Well, their "cure" is pretty close to killing the patient. I hope it was worth it to destroy the greatest economy in the world, for their petty, personal reasons. And they call us selfish???
