In response to TeeDee's point - No I don't think so. It might appear so, but if you need a qualification to get a job or interview then that's a direct return on investment that continues to accrue during continued employment. In many cases the actual qualification or learning may not be relevant to the job sought or needed in the job.
It might also create benefit at some point in the future, the learning acquired leading to later relevant work or, ability to generate income, such as understanding gold and silver prices and markets (since that's the origin of this thread). In my case, my early training has been of far more use since I started sweeping and installing later in life. But early on it got me an interview, and a very good return on my self-investment.
The tricky part is deciding how much to invest for potential return over a lifetime. I think some of the Uni's etc and courses are overhyped and over-priced. The cost of student loans also makes some courses not worth the investment/risk. If you invest heavily in say a medical course, and then find you don't like it, you are not likely to get a good return on other employment. If you've got the smarts, investing in a lower qualification/training in skills you can leverage can be a much better return.
