The least business requires a reasonable capital to start with and if you don't have an alternative means of generating this capital, getting a job is the easiest means through which you can build your capital.
To start a business, you will definitely need capital and those who do not have capital will definitely have no alternative but a job. However, many people lack sufficient capital and management in their business, due to which the only perfect job for them is a job. Again, many people have not had the desire to work and if they have enough capital, then if they can do their own business in their job and want financial freedom, then I would definitely say that they should quit their job and start a business.
