Been thinking about something that doesn't get enough attention: roughly 62% of American adults actually own stocks. Sounds like a lot until you dig into what's really going on.

Here's the thing that caught my eye - that percentage masks some wild inequality. The richest 1% controls about half the stock market's total value. The next 10% holds just under 40%. Then it drops off a cliff. The bottom half of American households by net worth? They collectively hold around $480 billion in stocks. That breaks down to less than $8,000 per household on average. And that's being pulled up by people who actually have significant positions. The median is more like $52,000, which is better but still not transformative for most people.

So here's what's interesting: this wealth gap exists partly because so many people never start investing at all. And that's the real opportunity cost.

The math is pretty straightforward. The stock market historically returns around 10% annually if you're patient. That's still the most reliable wealth-building tool for regular people, way better odds than trying to start a business or get rich quick. But you don't need a fortune to begin. You don't even need to pick individual stocks.

I've seen people get paralyzed thinking they need thousands to start. Wrong. What matters is getting in the game. An index fund tracking the S&P 500 is perfect for this - you get exposure to the whole market without the headache of picking winners and losers. Your returns match the broad market. Simple.

Let me throw out a scenario: someone putting $300 a month into an S&P 500 index fund for 35 years, assuming that historical 10% average return, would end up with roughly $1.1 million. That's not some fantasy number. It's the power of compounding working for you over decades.

The percentage of americans who own stocks matters less than the percentage who actually start, even small. Whether you're buying one share or a thousand, the percentage gain is identical. Time in the market beats timing the market every single time.

Even $50 or $100 monthly into a brokerage account or IRA is a foundation you can build on. Most people could swing that. The real mistake isn't having small positions - it's having no position at all. That's where the millions get left behind.
