Far more, although that’s largely due to compounding gains than actual work.
As an example very rough calculation with ~7% real returns causing doubling every 10 years would mean 1,000 dollars in 2021 = 2^20 x 1000 = 1.05M x 1,000 = 1B. So if you saved 100k in 2021 you would have ~100B (in 2021 dollars) in 2221, or 1.6T in 2261.
Historically this concentration of wealth was reduced substantially by shorter times between generations (18-20 years vs 30 today) and far larger families (5-6 vs. 1-2 today).
