It’s incredibly complex to accurately predict what will happen and this is entirely plausible. I can also imagine there being people who have (example) $10,000, wait a year for it to be $18,000, and spend the $8,000 as “free money”. Rather than saving it which won’t put you ahead of others as they also benefit from the 80% interest (perhaps more so). I’m guessing that’s why there’s the caveat of even capital distribution which hasn’t happened anywhere in the history of life on Earth at any point in time presumably.
