Brother schubert, I said there were parallels, not equivalents! I was speaking of your "I find the best done material is when it's done for love first and foremost" statement. In Classical, period-informed musicians and singers specializing in Baroque repertoire are not financially compensated as highly as are modern Symphony Orchestra players and Opera singers. But Baroque specialists are idealists, with a deep love and reverence for the music of that period's composers.
In Pop (non-Classical), while commercial Country singers are pushed by the music industry and often handsomely rewarded, Bluegrass songwriters, musicians, and singers earn relatively meager incomes. When Ricky Skaggs decided to make the move from Country (where he was doing very well) to Bluegrass, his record company did everything in their power to dissuade him. Bluegrass was considered uncommercial, and he was written off by the industry. He did it anyway, following his heart rather than reasoned career advice.
Another parallel is that the Bluegrass community---both performer and audience---shares with the Baroque era composers the Christian faith. Many Bluegrass artists include Gospel songs in their repertoire, some of them recording complete Gospel albums. Consequently Bluegrass festivals are very much family-orientated. I can't take my kid to them, as he's into Rap ;-) .
