> Some users spend $100+ dollars a month

IMO the real interesting questions your post brings up are:

- what kind of labor is the $100 your users are spending coming from

- where would these $100 have gone before your product existed

- where do these $100 go once they change hands from users to you

There are many answers, not a single answer, to these questions, but I think they're worth considering.

In a previous life I worked for a startup where, getting to know our users, I realized that if you broke it down the revenue was essentially money being funneled from hourly-wage workers to venture capitalists, which was a sobering realization.
