To what level does success happen because of education?

Unarguably, there are many people who have been amazingly successful and have achieved this without a string of letters after their names.

However, education does inevitably open doors. The world has become more and more competitive. You need to "shine" when up against your competition in an interview situation, for example. And frequently, the bench-mark for even securing an interview, is dependent on the level or relevancy of your education.

At a really simplistic level, having acquired some academic or practical qualifications is proof of a desire to succeed and improve one's lot and this can only reflect well on any individual who is applying for a particular role or position.
