That sounds very surprising to me. To me at least it seems it's getting easier, at an accelerating rate. With resources such as libgen, scihub, mit ocw, a great number of moocs, the amount of content is only growing (most stuff gets archived). Most top universities have publicly accessible course data and resources.
Also, internet access is growing, internet devices are getting cheaper, high speed broadband is also becoming the default.
So I wonder, why would you say it's getting harder to get a cheap high quality education? I'd say you can do it for free, just look at the mit challenge.
Surely, the only obstacle is the constant stream of distractions.
