We should also keep in mind that the term "business" is broad in scope. Even though we all agree that businessmen run the world in terms of finance, there are some businesses that do not generate a lot of profit. It is more of a hand-to-mouth situation, and such people will jump at the chance to become civil servants if the opportunity presents itself.
Owning and running a business is never easy, especially at that stage of buildup. I have seen businesses fail, so business itself carries a lot of risk, and only those in business understand the risks. Today, most civil servants run their own businesses to supplement their salaries. The salary may not be bogus, but the feeling of being on the payroll is always a good one.
