Lord Mndz,
To a limited extent, that already happens. With High Education countries focusing on products that use a lot of High Tech workers, and low education countries focusing on mass employment Corporations. Pushing the difference too high would would risk unbalancing the game, and require players to get unreasonably high/low education indexes.
High level Corps are already quite profitable, based on their base values. The larger differences in profits are caused by market situations. So if a high level product is being over produced, it's going to lose money, and if a low level product has a severe shortage, it's going to make money. That's a good thing, as it makes players balance the market, instead of just spamming whichever Corp has the highest level.
If you look that the employment levels for different corps, you'll find they already vary a lot. With some using x10 as many High Tech Executives as others. If you want to focus on the Highly Educated Elite, the game already allows you to do so, it just doesn't always 100% line up with game levels.
