Since the news of Elon Musk becoming a trillionaire came out,
On paper. All these figures are "built into" the company's production, not sitting there in the form of piles of cash.
I've been seeing a lot of reaction of twitter that I can't understand. Why are people angry with him?
Simple human... greed.

Some people are even asking why one man can have that much money while others don't have food to eat.
That's just how the world works - unbalanced. Why do early bitcoin investors have so much money now? It's a similar question. Is this a reason to blame them for having bitcoins?
Some are asking why one man can have that much money, and health care is not free, and so many other questions.
What is the connection between one person's personal wealth and healthcare, which he has nothing to do with?
Don't you people feel that is an entitlement mindset?
I think this is a mindset of idiocy.

He did not give birth to you, and he is not responsible for you, so why do people expect him to provide food for everybody and free health care? When has the world worked like that?
He will be responsible for sending us all to Mars (and feeding us, and providing
free healthcare and even air).

Why are people blaming a person for the lack of jobs and health care instead of blaming the government they elected into office to provide these things?
If start accusing the government of failing to fulfill its direct responsibilities, could end up in prison (as in some countries).

But there will be no consequences for cursing at Musk.
I'm not even a fan of Elon Musk; I disagree with a lot of his views, but I just cannot understand these reactions. And it's not just from Americans. African, Europeans, and Asians are all saying the same thing. I've seen a lot of very dumb reactions, and I like to know why people feel this way. I've even seen millionaires complain about a person being a trillionaire. How does it make sense?
Because there can be no sense (logic) in emotional behavior.
