Are you absolutely sure you're talking sense?Let us also not forget that the artist community of this generation, besides all the challenges you had mentioned, are economically and otherwise placed faaaaar more comfortably than the artists of the older generation. So in all fairness, if you are looking at higher returns (as what the current generation artists enjoy), then they better be prepared to take that much more responsibilities, and be under higher scrutiny.
Vidwans of the calibre of S Ramanatha Iyer, Srirangam Iyengar, MDR, to name a few, with soooo much dedication and sincerity to their profession had to undergo living standards not worth mentioning.
Yes, MDR never had a mobile phone, but neither did Indira Gandhi.
I don't know if it was as common for musicians to have to juggle another job for a decent standard of living in the past as it is now.
