It's certainly easier to make in today's music/entertainment industries too, thanks to such things as auto-tune but I'm not convinced on the 'old days'.
There are some talented singers, actors etc. in this error too. Even the greats of yesteryear were of a low count. less than a handful in each decade. That still exists now with the current crop.
Too much emphasis on the old school and too much hype for them too from the oldies, I feel.
