> The other way to get rich is to own things. If you own a factory or real estate or bonds you get to charge other people and make a profit even though you are expending no effort. And in this case there is no limit on your profit, because you can use your profit to buy more capital and make more profit from that.

Risk : Reward, that's obvious, isn't it? I have known many relatives who bankrupted themselves trying to "own" stuff. I also know some who succeeded and are rich. Starting a business is very hard, try it.
