I'd like to fly across the sky on a unicorn while drinking whiskey with a leprechaun, but it's not really in the cards.
How many bootstrapped businesses can you think of in the Fortune 100/500? It's very rare to get to that size without the capital to make mistakes. Bootstrapped businesses generally have very little room for risk, and the ones with business models that can both be executed on and monetized profitably to > $100MM revenue/yr can probably be counted on two hands (e.g. GitHub, Plenty Of Fish, Braintree, GoPro).
If you or even a small handful of people own 100% of a company, you don't need $100MM ARR to get rich beyond need.
You won't become Bezos but bootstrapped companies don't need to become unicorns to make everyone there be filthy rich. There are tons of people who bootstrapped companies and are very well-off from it.
Lesson: The people in the US quite comfortable financially rarely took venture capital.
"Hey, you have some capital, and we have this great thing that can serve the world. We're capital constrained, either for quality or for growth, how about we partner to make the world a better place?"
it's also really not obvious how, for so many different types of companies, you would scale up without being funded
Going public is also raising money--among other things.
