Here are two variants, meant to be completely independant of each other, that you can use to maybe flatten the field a little.
1) Random starting control. Each player on their first turn has the option of spending both actions and 5 MB to draw an extra card, which would be under their control. If it's a group, it is put on the power structure. If it's a special card, it's yours to keep and use later (perhaps for a privileged attack). It's random but allows something.
2) Chosen starting control. Each player on their first turn has the option of searching the entire deck (then reshuffling) to take over a group of their choice. It's not cheap. The group will cost 1MB per each point of Power, Transferrable Power, Resistance and Income. Doing this takes both actions. Shuffle the deck afterwards. The Income of the IRS would be based on the number of players at the table; the Post Office's negative income does reduce their cost.
Optional for each: each player has to write down if they will take advantage of the first turn special action or not and shows their choice on their turn.
