> Is it because 90% of Americans don't even have money left to invest after their cost of living? It's because it doesn't take all that much to live on when you retire, and to have more money requires working longer. Especially, most retirees get big efficiencies from using tax-advantaged accounts, so you have less invested, but you get more out of it. Those accounts have contribution limits, so they don't scale up for the big investors. I work on goal-based financial planning, and one of the key things people want is to retire sooner, which means saving less. If your financial plan was perfect, you'd drop dead with exactly the amount you want to bequest to heirs / charities in your portfolio and not a penny more.
