I know many many people are claiming degrees are useless: statistically they are not. Nearly in all countries when you have higher educational degree its more likely you land a better job. Yeah obviously all jobs pay very bad nowadays but its more of issue within economy where laborers are getting much less share of gross domestic product... I think if you have time and resources to get a degree - well, do it. It can also help you meet with people with better connection in campus you know.
I agree with you that if we have the capital or facilities to continue our education to a higher level then entering and continuing our education is also a pretty good thing. As long as we have enough finances to support the costs of academic education. As you said, sometimes we can build connections with many great people on campus. Like Mark Zuckerberg, who actually has acquaintances or friends he knew from where he studied who supported him in funding the development of Facebook (Sorry if I'm wrong but I think I've read his story about that). That is the importance of relationships or connections in building a business. And it can be built while we study at university.
