Previous decades you had to go to a university to get access to resources that simply didn't exist in the rest of the world. Large libraries, labs, lectures, etc etc. Nowadays the internet can provide vastly superior resources then any Library for the most part. Sure there are lots of stuff not yet on there, but that issue that isn't going to exist forever.
Quality courses exist for free. Lots of others are available for hundreds were at colleges they cost thousands. Access to experts is something you can pay for. Don't need to spend hundreds of dollars on books. Can concentrate on what is important to you and you can go at your own pace. People who want to network and peers can still have access to one another through meetups and online messaging. etc etc.
K-12 education is terrible for most people. You can get far superior education for your children by simply enrolling them in Khan institute and hiring tutors for subjects you are not great on.
People think you need to government to solve the cost of education, meanwhile individuals and companies have reduced the cost of education to nearly zero in most cases. Just won't get those special degree certificates that everybody covets. But that won't last forever either.
