Is it cost-effective to start your own company and pay social security yourself?

It is not cost-effective to start your own company and pay social security for yourself than to join other companies, because as employees, you can enjoy more benefits by accepting social security from other companies. A company has only its own employees, so it costs more to run social security for itself in the name of the company than to join other companies as employees and accept other companies to pay social security for themselves. Therefore, it is not a cost-effective choice to start your own company and pay social security yourself.
