When investing in a corporation, there is no guarantee that you will gain profit from it, you can even lose your entire investment.
If you were a long-term Nokia shareholder, you would have lost a lot of money since, say, 2005.
When you invest, you put the value of your previous work at stake. You can retroactively sink your work (= money that you earned from it) into a black hole.

What was the "previous work" I did when I inherited my father's Walmart stock?
Let us hope that they won't get sucked into plots of the next Bernie Madoff, who will likely come one day.

True, I was thinking about investments of surpluses from your salary.
In a modern economy most "business owners" are passive shareholders who literally do nothing for that money. I am a partial business owner of many enormous corporations via my retirement account. I don't do any work for any of them, and yet, they continually send me money. Strange!
