In fact, everyone wants to earn money, not only the rich are earning money, but they have more opportunities to earn money than the poor who do not have money to invest. So they don't have anything to invest, so they stay at their same place, they can't move forward, while what the rich have is more money, they invest what they have somewhere, then someone any money that he has starts getting ego, while the poor person stands in his place and earns money with what he has. If opportunities are not available, then he cannot move from that place because he has nothing to invest .
You won't get the opportunity if you can not see it. Rich people become more rich because they see the opportunity and use it to make money. If you take away all the wealth of a successful businessman and leave him as he is an average man he will still be rich if he gets some time in his life. Rich people have different mindsets and point of view about their surroundings. When some people are doing something for fun business-minded people do that same fun by at the same time they will figure out a way to make money from it.
