I noticed the new line in the balance page:
Total expenditure this round: 7.245.063
It immediately got me wondering how my number compared to other players. That brings up my request for a new highscores category. I'd like to see a ranking of total expenditure score. Maybe total expenditure/1,000,000. I think this number will be different from IT-Company because some players buy and sell a lot and will get a higher "power-broker" number, where players who produce all their own stuff could still get a high company value with a lower "power broker" number.
Technical asside: You could use the total expenditure, total income or an average of the two for the power broker rank. I like the total expenditure version better because players who hoard cash (IT-FatCat) aren't brokering power, they're storing it.
