The first reason why you can never be rich is too much responsibilities, carrying family problems on your head which we all know family problems are always around the corners and can't be totally eliminated. The best help to offer family is to put yourself in a better financial position, don't struggle to help family, struggle to put yourself in a better financial position then take away your from dependency. How do you take them away from dependency? If you have a company or business you are running or a connection, you can connect your family members to your friends let them work for them so that they can earn their own money or you have a business you are running, they can work for you to earn their own money. As long as their is still dependency they will continue to depend on you and demand from you.
Now you mean that because of familial concerns, he will prevent someone from being wealthy? I disagree with you; I don't believe that leaving your family in order to be rich is the best option; you can't make it without family help and prayers, and I don't believe we will survive if we don't help each other; even if you are in financial difficulty, that doesn't mean you will isolate yourself from your family because of the problems you have with each other. Now, if you don't own a business and only make money online, you can't support them if they are in need. All of the things you describe cannot prevent you from being wealthy.
Some people waste money because they do not trust investments, because they have been duped. The fundamental reason why more people do not invest is a lack of trust.They've been burned before, and the "once bitten, twice shy" syndrome kicks in. They are also unaware of the benefits of investing and the protection that is available to ensure that your money is not lost.
