I didn't want to clog up my post with extraneous numbers. However, if you want them, I can give them too.
Karma had only a 200 SDI wonder advantage. 170 WRCs. 219 FAFBs. With the exception of the the 800 MP advantage by Karma, the advantages weren't too large nor impossible to be made up, especially when you consider the fact that they include TOP+MHA on the side of Karma, which prior to the war buildup, was impossible to ascertain, as Bob Janova can confirm.
Taking their combined stats away from the previously aforementioned, that leaves the advantages -20 SDIs, +42 WRCs, +557 MPs, +68 FAFBs. So once again, I state, it wasn't as lopsided as you're claiming, by far, unless you're considering absolute worst case scenario.
Karma had a 3.911 Infra:Tech ratio. Hegemony had a 4.198 Infra:Tech ratio. Take out MHA+TOP with Karma and you get Karma's ratio of 4.034 Infra:Tech ratio.
Edit: Forgot to remove TSO from the scenario as well. Their impact switch would further level the numbers even further. removing another 40 SDIs, 25 WRCs, 30 MPs, and 14 FAFBs. That would bring the total to -60 SDIs, +17 WRCs, +527 MPs, +54 FAFBs. Karma's Infra:Tech ratio would increase to 4.071 Infra:Tech
