2 questions!!!!!! (Little Upsilon)

2.when set up a new corporation in the HIGH TECH, there are 2 corps (advance quality products and advance effectivity products)
those 2 are for what? thaks.

You shouldn't really need to nationalize any corporations. With the exception of strategic weapons based corproation. State corporations can be bought out by CEO's, this is beneficial to your country because it brings in more money, and you usually get paid more for the corporation then what it cost you to build.

Advanced quality corporations sell quality upgrades (no one really knows how there can be 270 different quality eggs) to all corporations, quality increases the value of the goods your corporation sells (including quality products, high and low quality upgrades?), efficiency is the same concept but instead they decrease the number of workers needed to run that corporation and increase the need a little of managers (less workers and more manages?) and high tech workers quite a bit.
