Some of them do ask for it. And it does little or nothing.

I'm a writer and a blogger. Newspapers are dying. If you put ads on your site, people use ad blockers. People find ways around pay walls. Etc.

Sometimes you can't somehow magically control the fact that people won't pay you.

Then you work on something else that the world wants to pay for or you continue doing something you love and no one wants. The world doesn't owe you anything.

The world might not owe anyone anything but the world is worse of if people only do whatever is the most profitable for them.
