I understand your point, but what would you suggest? after all, this is still just a game. If all of these improvements would apply to the entire race, two problems would immediately arise.
1. All 5 (or more) opponents in the game would also have these race-wide upgrades and could quickly use them to exterminate you. How would you like to face 5 opponents who all had the race-wide improvements that you described?
2. This interesting game element would become way too overpowered, and would have to be curtailed drastically - or even eliminated entirely. Would that be preferable to you?
If so, I believe that in the set-up you can reduce or turn off all of these game elements. Why don't you try that, and see if it makes your gaming experience more enjoyable.
