"A part of all you earn is yours to keep. It should be not less than one-tenth no matter how little you earn. It can be as much more as you can afford to keep." ā George S. Clason
In 1926, George Samuel Clason published a series of pamphlets on thrift and financial success, framed as parables set in ancient Babylon. These pamphlets were later bound into a thin book called The Richest Man in Babylon.
Thousands of finance books have been written since then, offering derivatives, crypto strategies, option-trading, and leveraged arbitrage. Yet Clasonās core premiseāsimple, ancient, and blindingly obviousāstill outperforms nearly every complex strategy ever devised.
The Fundamental Trap: The Zero-Sum Life
Most people live their lives like this: they get paid, they pay the landlord, they pay the electric company, they pay the grocery store, they pay Netflix, and then they try to save whatever is left.
The problem? Nothing is ever left. Parkinsonās Law dictates that expenses will always rise to meet income. If you pay everyone else first and save 'the rest,' your 'rest' will mathematically gravitate to zero.
"Pay everyone else, and you become a slave to the ecosystem. Pay yourself first, and you become its master."
Running the Babylon Tenth: The Modern Calculation
Letās translate 'one-tenth' into the modern financial landscape. Say you earn the median U.S. salary of roughly $60,000 per year. Ten percent of that is $6,000 per year, or $500 per month.
Many people say, "I can't live on 90% of my income!" But the truth is, if the government raised your income tax by 10% tomorrow, youād complain, but youād survive. Youād find a way to make it work.
Here is what happens if you tax yourself that 10% and invest it in a simple S&P 500 index fund averaging a historical 9.5% return over a 35-year career:
- š° Monthly Contribution: $500
- ā³ Timeframe: 35 Years
- š Rate: 9.5% Annual
- š Total Cash Invested: $210,000
- š Final Nest Egg Value: $1,625,880
Out of that $1.62M, only $210,000 came from your wallet. The other **$1.4 million dollars** was generated automatically by your 'silent slaves'āwhat Clason called the golden coins working for you night and day.
The 7 Cures for a Lean Purse
Clason laid out seven cures for poverty. Let's translate the most impactful ones into 21st-century language:
- Make thy gold multiply: Don't let savings sit idle in checking accounts. Get them into assets that produce yield.
- Guard thy treasures from loss: Avoid get-rich-quick schemes, obscure altcoins, and things you don't understand. Safety of principal is paramount.
- Make of thy dwelling a profitable investment: Live in a space that builds equity rather than draining your soul.
- Increase thy ability to earn: Invest in your own skills. The strongest asset you own is your own mind.
The Call to Action
The Wisdom of Babylon is timeless because it works within the constraints of human behavior. Don't overcomplicate it. Set up an automatic transfer of 10% of your paycheck to an investment account. Pretend that money never existed. Years from now, you will look back at that single '10%' decision as the fulcrum upon which your entire financial life pivoted.
