Everything is in the title I presume...I think the best would be to do a new technology that would eventually increase that effect(the free market/planned economy should be factor too) but if you don't have the time to bother with that just please put it in a text file or something.
The fact is that if the same ratio is applied to every nation in the world it will lead to strange results, the wealthiest nations would be China and Soviet Russia which is rather strange. Millions of peasants in fields generate very few income, while a few thousands high-qualified workers are really needed by the economy and so if they were to be drafted the national economy collapses or suffers a major crisis. So I would see a very low ratio for undevelopped nations and a much more higher one for industrialised countries. But again, I know you have 2 months left so please just make it moddable.
