Investing with little capital do not yield massive profit when compared to investing with big capital.
It will make one loose so many good investment opportunities as there won't be the possibility of diversification of investment etc.
This is quite important to remember. When you compare people with a much larger investment to someone with small investment with the value of their investment, obviously the larger will be the someone who will look richer. However, if you compare them both with the percentage of the growth of their investment, then you could tell who is exponentially becoming richer.
