If you make on average, $100k a year over a short 30 year career, saving only 10% at .1% APY, what are your savings? $314.5k. What if you invest instead and earn on average 8%? $1.2MM
How about over 40 years? $418k vs $2.8MM.
Compound interest has and will continue to be a major driver for wealth throughout the world. Reducing its benefit to a moral argument of the rich getting richer is sad.
Many of the richest Americans are taking part in the giving pledge, allowing their wealth to build and take advantage of compound interest over their lifetime and giving a large portion of it back. The alternative is giving 40+% to the government each year, who will not be earning compound interest with it. https://givingpledge.org/PledgerList.aspx
Compound interest coupled with the fact that people can’t take their wealth to the grave makes for a natural ability for money to both amass quickly and then be transferred back to the public or to heirs or wherever else.
