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 .
No body makes more money than the rich because they are ready to take what ever risk that it comes with. And why they will have more opportunities than poor people is because they will always have money to invest any time any moment. But the poor will have to look for money to invest. So that is different between the poor and the rich. And in time of physiological thinking the rich is also better. Because they always have the mentality of adding up to what they have got. And even when they buy rich people can also hold better because they also have money to solve there problems. And the poor is always full of one challenge or the other.
