I think One of the reason why people remain poor even while earning a decent amount of money from their businesses is the fact that they see money as a spending means and not investing....
         When building a business, it requires some level sacrifice and discomfort, after there have been significant growth l, money can be spent for expanding the business. At this point, it is not  referred to as spending but as investing, because the changes and expansion will bring in more profits.
         However for the case of people earning salaries, do you think there is a way they can be really rich without owning a business and or is it compulsory for one to be own his own business
