You've put your finger on an important issue. For the person with a degree, there is an advantage in passing that barrier to entry. But why is that barrier to entry there?
From the point of view of the employer, a degree indicates that the possessor has, among other things, a certain level of intelligence, literacy (not a small deal in a country where over half the country is functionally illiterate!), experience in learning, general background, work ethic, and socio-economic status. It is therefore a somewhat useful filter to apply for many professions.
Of course most of those traits have nothing to do with what you actually learned in university. And there certainly are plenty of successful people with all of those traits who did not bother with university. So even though I believe that for most people, education is worthwhile to that person, I'm far less certain that society as a whole benefits much from all of the money spent on higher education. (And I become even less certain when I look at how wasteful the process has become. Costs have been going up faster than inflation for decades, with no apparent reason than that everyone in the process knows that they are free to raise costs by that much, and it is always easier to spend more money than it is to spend less.)
