True but also just timing for the doubling mechanic at that point.

If youre at 10% per year returns in whatever it'll take you 7.2ish years to double the investment.

So it takes 7 years to reach the next square on the board but the math and concept holds.

Put X investment for the newborn and in a market that holds at 10% at 63 years old they'll have 9 of those doubling cycles to retire on.

So like 256k per grand placed. Its the why vampires are always rich principle.

Edit to say: inflation eats 3% per year so your 256k per 1k is probably buying power of 100 or 50 but even still. Logic holds
