Motivation in life is needed to be a better life. rich people and artists can be role models, see or research how they can make money easily and succeed in becoming a billionaire, because money today is everything there are many ways to earn money all racing contest
Being able to work with people in the art industry (music, dancing, illustration), I would say that it really is not easy to make money from art. Most of the newbie artists never make it. A lot of them are good but are never paid for the amount that they should. We always only remember the successful ones but the art industry is full of people having to work in the corporate industry just to survive life because selling their artworks aren't exactly profitable.
Art industry is business and you have to be a businessman while being an artist in order to get paid for it. You also have to be known. You need loyal buyers and you need a wide range of audience. Your art has to be liked by the mass before you can make money from it. We see artists out there, especially singers, becoming celebrities and making tons of money from their art. But behind all that is a team and a lot of people helping that artist make it. A lot of sacrifices were done and hardships had to be faced for an artist to even make minimum wage from doing art. They don't just do art and then get rich from it.
Money is important, it is an important determinant of what people do and don't do. That said, we always leave room for other motivating factors; religion, love for country, humanity, love for people, the desire to be recognized by peers and society... and the list goes all. Money is something, it just isn't everything.
Others have the luxury to do something without getting paid for it. People are helping other people to ultimately feel good about themselves, to feel like they are better persons than they were. The rest of the people are doing everything just for money because that's what they need the most. They don't have the time to be soft to people and show kindness because they, themselves, are in need of help.
