I think you can't make money without a lot of effort. So you have to work hard to get some money.
There are very few people able to get that kind of wealth but the important thing is that no one really needs that amount of money, as long as you can use your money to get a good life that is all the money you need. My beliefs about money and wealth is that manage and have control on your money or wealth, if you have plenty of money you could help others who are in need because I believe if I can help others , my money will grow
