Will the world's richest person in 2033 have a net worth greater than that of John D. Rockefeller in 1913?

John D. Rockefeller is considered to be the wealthiest American of all time. In 1913 he was the world's richest person with a net worth of over a billion dollars. That was equivalent to about 2% of the United States' GDP back then. For reference, 2% of US GDP would be close to 400 billion dollars today! This reference perspective makes him much richer than the current richest person in the world, Jeff Bezos, whose net worth is at 112 billion dollars in the 2018 Forbes ranking.

Yet, inequality is on the rise in many developed countries and the net worth of the richest person in the world has been consistently increasing over the last few years. Could a person as rich as John D. Rockefeller reappear in the modern world?

It is asked:Will the richest person in the world in 2033 have a net worth equivalent to or greater than 2% of the United States' GDP at the time?

Data for resolution shall be taken from the 2033 Forbes Billionaires list (note: of course the link currently does not lead to the 2033 list). Note that this list is to be differentiated from the real time list.

Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available. With tachyons you'll even be able to go back in time and backdate your prediction to maximize your points.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Community Stats

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
