Grad schools are now offering online equivalents that are treated seriously (e.g. Georgia Tech especially) at affordable rates.
Even when I had courses in university, sometimes there was an online version of every class. Why spend the effort of going to class, getting ready, when you can just watch everything at 2x playback speed?
There are some classes that require hands on learning. But these are far and inbetween, and mostly are STEM related anyhow. You can't replace the collaborative experience, social connections of a college campus. And wisdom from an instructor, or those connections. But you don't need to go through that twice (grad school - unless for research) and tuition costs for online grad degrees are only lowering down for these
