Should the poor consider investing as a means to becoming rich?
Given that a poor person probably has much less to invest, how can odds be in their favor? To add to Lan's great answer, if one is "poor" because they don't have enough income to build wealth (invest), then there are only two ways to change the situation - earn more or spend less.  Neither are easy but both are usually possible.  One can take on side jobs, look for a better-paying career, etc.  Cutting spending can also be hard but is generally easier than adding income. In general, wealth building is more about what you do with your income than about how much you make.  Obviously the more you make, the easier it is, but just about anyone can build wealth if they spend less than they make. Once your NET income is high enough that you have investible income, THEN you can start building wealth.  Unfortunately many people have piles of debts to clean up before they are able to get to that point. What could a small guy with $100 do to make himself not poor anymore, right? Just having $100 is not going to make you "rich". There is a practical limit to how much return you can make short of high-risk activities like gambling, lottery tickets, etc. (I have actually seen this as a justification for playing the lottery, which I disagree with but is an interesting point).  If you just invest $100 at 25% per year (for illustration - traditional investments typically only make 10-12% on average), in 10 years you'll have about $931. If instead you invest $100 per month at 12% annualized, in 10 years you'll have over $23,000. Not that $23,000 makes you rich - the point is that regularly saving money is much more powerful than having money to start with.
