What is business?

I have observed a quite interesting phinomenon. Many might have already did. Business is all about looking for opportunities at the right time. During the economy boom, the rich have seen an opportunity in real estate. They became richer and the middle class guy realized he has missed an opportunity. During the economic boom, the middle class guy wasnt very sure of the economy and didnt dare to invest whereas the rich did. Similar is the case of migrating to America. The rich guy saw an opportunity in America. He didnt fear taking into account that there are not many Indians in America at that time(around 2000). He got rich and became a citizen. The middle class guy went to America only after he is convinced that there are a lot of Indians in America and hence dared to migrate to America. But by that time everything got over. There is no more opportunity in America. This is the typical mindset of a middle class person. He realizes the opportunity after the rich has already realized and the when trend is already over.
