Regarding going to a VC to get capital: think about how this process works in one very tiny slice of the economy. You build trust with a small set of people that are the arbiters of capital and who gets the resources to start a new venture. If there was only one VC firm in the valley, it would be disastrous because they would hold all the power. It is only through the agglomeration of many potential sources of capital that really makes the system run well.
In the rest of the economy, there are few VCs, and for a lot of profitable, but smaller businesses, capital is super hard to come by. A person who sees a future in, for example, electrification retrofits of homes and has several good ideas about how to make it cheaper and more economically efficient, is going to have a really hard tome getting going. However, if their own community knew about this person's ability to scale a small business, and knew of the intelligence and grit of a person through their own personal relationship, and if that community had small amounts of capital to throw in to get the newcomer off the ground, overall wealth is increased as the new venture starts serving the needs of people.
But this requires more equal distribution of capital, and to change the arbiters of capital from a few hundred people to everybody.
I don't really hear many people talking about friends, family, and fools rounds these days because the game has changed. However if we had more people that could use their knowledge of the local lay of the land to invest more wisely, we'd have far greater wealth generation.
IMHO, the problem with inequality isn't the person with $100B, the problem is all the talented and skilled people whose ideas go to waste because they can't get the attention of the very few people that have been entrusted with the ability to allocate capital.
The more inequality there is, the closer we get to central planning, and erasure of the talents of so many people.
