well, their is a way to do something like that.
if you IPO a corp at the lowest possible value. 600B, and you buy the max shares (40%) for a secondary country's Investment Funds, it'll cost the IF 240B. Then after the corp value increases, to say 1.2T, you sell out, doubling your money. Their is a little more to it than just that, but yes, it works.
if you compare that "profit," to 40% of the corps profit it will pay out, via dividends, You'll realize that you will literally increase your IF by RL years, compared to the daily dividend.
The Game Masters estimate the over all profitability of corps, based on the total Market value of all corps. so in order to prove that their game changes make us all more profitable, they increase the MV, but market value has always been ridiculously high, compare to actual profit.
