I believe if we confiscated all wealth and redistributed it equally, within 10 years the distribution curve would look almost exactly how it does now, and within 50 would be basically identical.

It would be much quicker. The vast majority would be convinced of something like "your newfound wealth isn't safe from your neighbors, we will hold it for you 😇"
I asked somebody on Reddit LOL a couple months ago and if you were to take all the billionaires in the world and give their money to everyone equally. It would equal out to everyone getting around I think $1,800 each like a thousand eight hundred
Wealth formations depend heavily on the structure of the money. If you redistributed all the wealth equally tomorrow, and kept the current rules of the system in place, it would look largely the same in 50 years (although probably not at the edges)
If you change the fundamental structure of the money, the wealth distribution will change with it.
As long as rampant consumerism and headless hedonism is the norm, this would be correct.
