Literally Amazon is the only company because of which I feel comfortable right now sitting in my house vs. panic buying.
Amazon and Bezos should certainly be taxed their share. I for one don't want to support tax avoidance/evasion and theft from labor. They're not running a charity work or a public service disguised as Amazon marketplace (there is Amazon Smile to be fair) by any means, at least not to my knowledge.
Amazon doesn't make me feel any bit safer and no business should be capitalizing on panic buying, be it a local business or Amazon.
They're running Amazon and hiring more workers because there's a massive opportunity to further stamp out their retailer competition, solidify their foothold further, and make money... not out of the goodness of their investors hearts. It's about money/business opportunity, not your security.
Nothing wrong with that.
In a pretty shitty one. That is the ultimate goal of modern cut-throat capitalism: get utter market domination, destroy all competition and once that is done, raise the prices as far as possible without attracting too much protest from the few regulatory institutions that remain.
