In general idea is nice (and narrative/flow is going fine) . Passages about the numbers fits well into something like a dark corporate thingy. But there is a few things to mention (and probably to fix): 1. oxygen -- that's shouldn't be so rare and should be cheap (it might be found everywhere, the only problem is a cost to extract it, but here we have a Mars economy, means to sustain it this community already has a lot of energy production). 2) fixed price -- in a real world prices are going up and down, in the future they are more volatile. Probably it's not so important in your novel, but ... that's my opinion. 3) Heluim-3 might be a good source for fusion, and again -- you have a fusion, so didn't see a problem to extract oxygen ...
no offense intended -- that's just a few technical notes. anyway the general idea is good, keep going!
