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
Some people are collecting salary but in a way that they still have enough to safe after spending on basic needs and necessities. There are many of them that save and later open a business. But this can not be for those that have low income which may not be enough for saving up to what they can use to establish a business. Not everyone will be able to. But regardless of what someone is doing, having a business is very good and it can be very helpful
Everything in life have hierarchy. There are some people that their salary is very huge. But I think they will also later prefer to have businesses.
