I think the world will be a better place without notice or segregation between the rich and the poor if Bitcoin is embraced fully since Bitcoin is not a currency of a particular country everyone has the equal right and power to either store it or use it.
Your point here is very important because if all rich and poor people of the world or all traders use Bitcoin, then Bitcoin will help to eliminate the differences between people. But mostly those who are doing big business or managing an organization. In their case, they may not make a full investment in Bitcoin at some point but some people have. Those who are very smart tend to store bitcoins as well as some other currency, which serves as a reserve for them later.
