When the only way to hear a symphony was to hire an orchestra to play it every time, it was easy for a musician to make a living playing symphonies. Now that you can record one playthrough once and reproduce it for free, it's much harder - supply goes up, so the price goes down.

Substitute playing music for your creative endeavour of choice.

That's bullshit. Most of the greatest music compositors through History were broke as shit, even when being famous while being alive.
