Two jobs. One decision.
or: why doing nothing is its own kind of risk
The two jobs of money
preserves what you have. The number doesn't grow, but it doesn't vanish on a bad week either: perfect for money you'll need soon. puts your money to work in productive assets so it grows over time. Slower than the news cycle, but the only thing that for decades.
The savings account illusion
Cash sitting in an account looks safe, the number doesn't move. But what it buys does. is a slow leak: at 3% a year, $10,000 left untouched is worth $7,440 in real terms after 10 years, and just $4,120 after 30. You didn't lose any money on paper. You lost more than half of it in real life.
The cost of not investing
Now compare. The same $10,000 invested in a broad at a 7% real doubles roughly every decade. After 30 years it's worth around $76,000, in today's money. The gap between the two outcomes isn't a small detail. It's the difference between standing still and putting time on your side.
Same money, two paths.
Cash drained by inflation versus invested at a 7% real return.
When each one is right
The question isn't 'savings or investing?', it's 'how soon do I need this money?' The shorter the , the more you want certainty. The longer the horizon, the more you can let work for you.
You need it instantly. Returns don't matter.
Must be there on a bad day. Earn what you can without losing certainty.
Too short to recover from a stock dip. Preserve, don't grow.
Long enough to take some risk, short enough that a crash hurts.
Time absorbs volatility. This is where does its work.
The risk isn't investing badly. It's not investing at all.
When you have decades, sitting in cash isn't safe, it's the most expensive choice. You don't lose money on a single bad day. You lose it slowly, every year, while the world around you gets more expensive.
