This is another topic that's been talked about a lot, but is still a MAJOR flaw in the games economy.
It's been brought up on stream before(1 week ago), and he seemed shocked that it could possibly be 15:1, when this has been reported for months.

Reason why 15:1 is so broken:
1) Net Income buildings, and any other building that increases Income should almost never be built; You're better off destroying ships and rebuilding them, then wasting Credits on upgrading them due to Credits being such a terribly inefficient resource.
2) All economic policy becomes a base 2 system. You either have your planets set to Manufacturing or Science, or some combination of both.
3) The ONLY reason to build Income buildings is to keep your Total Reserve above 0. That's when it affects your Manufacturing/Science.

Obviously, instant purchasing(Rushing) has it's own inherent value that can't be calculated. But it's certainly not a difference of 14.
You can try to tell me investing in Income so you can upgrade your ships before battle can be worth it. My fleet that's now 5 times bigger than yours because you invested resources in Income producing sources will beg to differ.
The GalCiv2 ratio was like 8:1(or something close to that) <--This seems reasonable
