Once a company starts operating, but before revenue (and hopefully eventual profitability), the valuation is trickier. The share price _should_ be the number of shares divided by the sum of all future profit (minus current debt.) Which is hilarious of course, because no one actually knows the denominator.
That original $2M equity stake can grow to billions if the company ends up making something that a lot of people want or need, so the sum of all future profit is large. Or, much more likely, it will be worth nothing, or a modest amount.
Graham's essay kind of avoids the point of whether ownership of a vastly appreciating asset is "fair", if a bunch of other people help that asset to appreciate.
Another far more sensible model I've found is slicing pie. Each founder's input % of the pie pre-'bake' is their % of the rewards. And what makes up for one's slice of the pie? The dollar-value you would've earned if you worked somewhere else, times the period of baking. These can be tweaked accordingly to the type of investment put in. IMO, it seems far more grounded compared to say a flat 10%.
Why are you presupposing the world is just when EVERY skill and opportunity is distributed non-linearly?
Is that skill?
Most people with millions do not become billionaires. So yes, there is an exclusive pool of players who can play the game. But within that pool there is incredibly different outcomes.
A better analogy is being born as a child of D1 basketball athletes and then making 100 million in the NBA. Being born into a family with no interest in athletics makes it almost impossible to be a professional athlete. Life isn’t fair. It’s still impressive to become one.
If someone has an idea that 'only' makes them 20 million, I would call that a great success; even if it takes dozens of years to get there.
But this kind of person isn't rare either, even in Italy or Poland where I live I know many multi millionaires.
Some are farmers, some have restaurants/hotels, some work remotely for US tech companies, some were early engineers in startups.
