First of all, education helps you to lead your life in this complex world. Education is more than what they teach in school. It is the set of skills, knowledge, meaningful behaviors that you learned.
Education enables a higher income
You can work elsewhere and make money. You are in a good negotiating position, more independent because you have more options. More education enables more perspectives and thus more arguments. With the right rhetoric, you can explain to the financier what your value is, why you need how much money or why your offer becomes particularly interesting as the price increases.
