It helps us realize that business is more than simply putting out a shingle and hoping that things go well. There is a knowledge component to success.
There is a learning curve associated with success. Having business knowledge before you try and engage in profit seeking behavior is helpful. Training, education and knowledge help people successfully navigate the business environment.
It is also likely that knowledge and skill raise the confidence of people who want to start a business. It will be pretty tough to get out there on your own unless you believe you will be rewarded.
Furthermore, our ability to understand technology and quickly learn the business environment is also based in existing knowledge. Technical and vocational training offers background knowledge that puts everything else in context.
