>You should care if you already don’t. He runs some of the most successful businesses and people are in long lines waiting to get hired by his companies despite the high workload and below competition (e.g. facebook, google) pay.
Except that I really don't care about him though and it works well for me so far. With the risk of getting downvoted, people give him and other tech billionaires far too much importance.
My life would be exactly the same without any of his products. I can easily live without PayPal, Tesla and SpaceX, while my life (and everyone else here as well) would not be possible without the products from traditional "boring" companies that nobody cares about anymore, like wind and hydro turbines from Siemens and GE, healthcare devices from Philips, Siemens and GE, semiconductors, jet engines, planes, trains, etc.
