Besides, the reason why the power law distribution here is exceptionally skewed is precisely BECAUSE of technology like the internet. If you read about the history of music, in the past before technology, all musicians made less but at least there were places for local musicians to play in a strong community such as in local pubs and such.
TECHNOLOGY created the problem of the extreme power law and now it's disguising itself as a solution. But like the devil, a company like Google does not offer anyhting for free.
The barrier of entry is a business one, not a talent or skill one. Every country in the world has virtuoso musicians who don't earn money. Many/most of the hugely successful musicians released music that could be recreated pretty convincingly by amateurs with a few years of experience (vocals are probably the only exception as we strongly associate them with individuals).
