Yes, initially it will be available to the super rich. It's not due to exploitation though. Any groundbreaking technology costs A LOT, when it is initially launched. That's just the way it is. Do some research into how much launching a rocket to space costs today (even after all the progress recently by these private space companies).
But what always happens is that, over time, as more progress is made, and as more and more people are using that tech, it gets cheaper. That's just the way technology works. So, in a way, those rich dudes using it in the beginning are actually helping in the long run to make this available for everyone.
