I think you meant hoard incredible wealth?
There's a limit to how much wealth you can actually create with immaterial entertainment alone. Even a best seller book: it takes time to read, so while it provides value to millions of readers, it also removes value in the form of opportunity cost. No way around choosing what to do with your own time.
Other alternatives have more potential. Educational content could lift some people out of incompetence and help them build actual wealth (say a very good programming or sawing tutorial). Writing useful software could also create wealth, even more so if it's Free (and free). And of course, building stuff (while taking care not to deplete our resources or burning up our planet…).
We say that people "make" money, but that's a dangerously misleading idiom. They don't actually make money, they extract money. Hopefully this money is actually earned in proportion to the value they actually injected into society (make a chair, get paid for the chair, all fair and square). But never forget that the people who "make" the most money generally do so by taking it from other people. Employers, landlords, stakeholders… who get most of their "earnings" not from what they do, but from what they own.
