I am a scientist and thousands of scientists and engineers use my work.
Most great artists, musicians, writers, theorists, scientists, teachers, and inventors would not need to struggle as much if they would have some money to cover their basic needs. They would just avoid bullshit gigs and do they stuff with a greater focus. And if having $1M in their bank account would stop them doing what they love, then it is quite possible that they didn't love it in the first place.
Artistic pieces or songs are generally a representation of an event, a struggle, or a state of mind - if you lead a cushy life then no, you're not going to have the same output than if you were living on the breadline. There's a reason that history is dotted with songs and pieces of art that were written during times of struggle.
