> But there are very few slots available

Is it really true?

Personally, I'm evidence for it, since I spend my days building pyramids, and program only on the side.

But the entire thing does not add-up. The artful activity is so much more productive that I can not stop believing that in any market you are able to create a slot doing it, you will outcompete all the pyramid builders. (Yet this pyramid pays me too well to just abandon it.)
