I would love to do something like this but simply cannot afford it. I think it is good advice but going back to school for a degree one does not plan on utilizing is not as feasible today as it was in the 80's, largely due to the sizeable increase in tuition without reciprocal increases in wages.
Depending on where you live, and what you want to study, you might be able to take a couple courses at the community college in areas of interest without spending a lot of money.
I was paid to get a PhD in Biology, albeit just enough to live on. Most people in PhD programs are, either through being a TA (teacher's assistant) or RA (research assistant). The real financial cost is the opportunity cost of 5-6 years of your life.
Whether or not broad support for training scientists holds up during and after the current administration remains to be seen.
I'm pretty sure it's still the case that you get paid to be a graduate student in science.
My current tuition is under 500 CAD per class. The opportunity cost of not working full time is the real bulk of the cost of studying in places that have a functional government.

Work for a company that will pay for it.
In this day and age, you can do this for FREE and on the side, whenever you have time!
There are tons of very well-done professional level video courses on Youtube.
There are more organized courses that only ask you for money for the "extras", like some tests and a certificate, but the main parts, texts and videos, are free.
You could start with a really good teaching professor (Eric Lander, MIT) and his course: https://www.edx.org/learn/biology/massachusetts-institute-of... (the "Audit" track is free, ignore the prices; also ignore the "expires" - this course restarts every few months and has been available in new versions for many years now)
It's very engaging!
There's similar courses for everything in the life sciences, there on edX, on Youtube, many other places.
I feel the true Internet is soooo underutilized by most people! Forget news sites, opinion blogs, or social media. Knowledge is there for the taking, free. Only the organized stuff, where you end up with a certificate costs money, but they usually still provide the actual content for free.
