What you're referring to are called "expenses". The value created is what somebody is willing to pay for a piece of that action (i.e. an ownership share). Expenses reduce the value.

For example, if you bake a cake the value you created is what you can sell the cake for minus the cost of the ingredients and the use of an oven. For SpaceX, the money spent to buy materials and pay employees takes away value.

> that nobody could ever reasonably spend into the hands of one person (especially when that money is just the excess value produced by the workers) is unethical and unneeded.

Musk doesn't spend much of his money. He invests it in creating more businesses.

> is unethical and unneeded.

You're arguing that Tesla, SpaceX, Starlink, etc., are unethical and unneeded. None of those companies would exist without Musk investing his fortune into them.

BTW, why don't you and your friends get together and start a rocket company and make yourselves billionaires?
