A Solution for DCity

The current economy of DCity is the logical conclusion of its rules.
The game has always had two currencies, with a fixed exchange rate assumed through the price of random cards.
Changes in the market HIVE/SIM price can motivate changes in behaviour.
However, the two currencies have also developed into two economies with different tactics.
Those tactics have led to a disconnect between the SIM economy and the HIVE economy.
Worse than that, one side of the economy is able to influence the other side without any feedback in the reverse direction.
Hence, it is now possible to protect one's HIVE earnings by selling SIM earnings thereby increasing SIM taxes further.
This allows the HIVE-earning cities to continue to earn, grow and multiply.
There is nothing any President can do about this.

The solution is to tax HIVE earnings in the same way as SIM earnings.
The DCity game will last longer and we may see a miraculous change in tactics,

This is very easy to implement.
If we wish each President to actually have something to do, then we could leave the current tax options as they are and just take the Income Tax figure for SIM earnings and apply only that to the HIVE earnings.

Easy!
