I don't discount most of your arguments, as they are very valid in multiple situations... but not all.
Looking back we see things more clearly, or do we? We might see them based on the bias that we've created for ourselves or that of society that gets beat into us everyday. I only state that because everyone states how one can get a job if they work hard enough, take the right classes etc. And this is true if you want to stay as a coder.
As a hiring manager, i look for experience, but i also look at education, both degrees and continuing education. But i also look for people in higher level positions. Most people don't make it past HR if they don't have a degree. Why is that when in this day and age, anyone experienced can get a job?
Is it because a college degree means your more well rounded? Is it because someone with a degree is better than someone who has equivalent experience? Is it because a person with a degree has a better personality than someone who does not? No, its because it shows the ability to commit to something, to take it seriously. The same way as getting certifications. A degree opens doors as a person WITH a degree gets looked at for higher level positions over a person without in most interview situations.
Experience is important, but it is not everything.
In order to succeed in life, you need steady cash flow, i know everyone talks about that as a stepping stone to success and wealth. Without a foundation for that, where will you have the money to get that business off the ground? Who will give you a loan without a well paying job? How do you get experience as a real estate investor without having properties or money to purchase them?
The vast majority of people don't have the cash to buy outright, if you do, good for you! But to make that money, you need to have a good paying job.
I know there are success stories and horror stories of people with education. "I know a CEO who worked at Starbucks. I know someone with a masters in english or sociology who is flipping burgers." But how many people do you know who do not have an education that work at minimum wage? Is getting "A Job" good enough to pay for you or your family's future?
Is going to school the answer? Maybe or maybe not, but i'd venture to say that more professionals look to real estate as a supplement to their income, a way to build wealth than those that look to build it as a career from the ground up.
Sorry to ramble, hopefully i made some sense out of this post.
