> A restaurant won't scale - most ideas won't scale - because they're not useful enough

Counterexample, a restaurant worth $202 billion: https://stockanalysis.com/stocks/mcd/market-cap/

One of the arguments against billionaires really deserving that much money is that while they own the shares, the scaling up is done by a labour force that doesn't capture this growth, "only" (so goes the argument, I do know about share options) "their wages".

How many burger flippers get compensation in the form of shares in the parent company? I genuinely don't know, but I do expect it to mostly be in the form of pension funds rather than stuff they can see in their working lives. Pension funds are a lot of money, they need to be so those with them can retire, same logic as FIRE because being a pensioner is the first three initials of FIRE.

This is probably for the best, owing to something not explicitly mentioned in the article: startups are risky. This is as much a lottery question as it is an effort question, because "cool idea" absolutely does not mean "make it and they will come", no matter how hard working the founders (and first hires) are.
