Poor Richard's Almanack — Every Money Lesson

This is Franklin's warning about lifestyle creep and invisible spending. Small recurring expenses feel harmless in isolation but compound into wealth-destroying habits over decades. A $200/month subscription and convenience bundle that feels trivial is $2,400/year — invested at 7% over 30 years, that's $243,000 in foregone wealth. Franklin's "small leak" framing is precise: you don't notice a leak until significant damage is done. The antidote is regular auditing of all recurring expenses.

Consumer debt at modern interest rates (20%+ for credit cards) is one of the most reliable wealth-destroyers available. A $10,000 credit card balance at 22% interest costs $2,200/year just to tread water. Franklin understood that debt creates not just financial but psychological burden — obligation to future creditors reduces your freedom and decision-making quality. He used strategic business debt early in life but was unambiguous about the cost of consumer borrowing.

This is the clearest pre-modern statement of the difference between needs and wants — and the slippery slope from discretionary to compulsory spending. Buying unnecessary things on credit or from savings means you eventually must sell things you actually need to cover the shortfall. In modern terms: impulse purchases funded by debt lead to a vicious cycle where servicing past consumption crowds out essential spending.

The core insight of FIRE, stated 280 years early. Most people optimize exclusively for income. Franklin recognized the ratio — what you save as a percentage of what you earn — is the primary determinant of wealth accumulation. The FIRE community's research confirms this: savings rate, not income level, is what determines your retirement timeline. Someone saving 50% of $60,000 reaches financial independence at the same pace as someone saving 25% of $120,000 — same absolute savings, identical path.

Beyond its surface meaning, this is about the compound effects of consistent disciplines. Franklin's own extraordinary productivity — running multiple businesses, conducting scientific experiments, writing extensively, doing diplomacy — required systematic habits. The "wealthy" element isn't magical thinking: structured routines improve decision-making quality, reduce impulsive spending, and create the cognitive bandwidth to manage finances carefully. Sleep deprivation alone increases susceptibility to financial impulsiveness.

Extreme framing, but mathematically defensible. Consumer debt at 22% APR means every $1,000 borrowed costs $220/year. Compared to the discomfort of temporary austerity, the ongoing burden of high-interest debt is almost always the worse choice. Franklin's vivid framing — going hungry tonight vs debt tomorrow — captures the asymmetry: short-term deprivation is finite, while debt service is ongoing until eliminated. This is the core argument for building an emergency fund before investing: eliminate the conditions that force emergency debt.

In the context of compound interest, this is mathematically precise. Ten years of investment compounding lost between ages 25 and 35 cannot be recovered by investing more later. The math is unforgiving: $500/month from age 25 to 65 at 7% produces $1.31M. The same $500/month from 35 to 65 produces $567K — the 10-year head start is worth $743,000, and you cannot earn that difference back with higher contributions because the compounding period is irreducibly shorter.

Franklin considered consumer debt a moral failing as well as a financial one — because debt makes promises about your future self's behavior that you cannot guarantee keeping. In modern terms: debt is a claim on your future income. High debt loads reduce your future optionality, increase your financial fragility, and force you to prioritize debt service over wealth-building. Eliminating debt is one of the highest-return, lowest-risk financial moves available — debt payoff at 22% is a guaranteed 22% return, better than any investment.
