First, I would like to congratulate 
I feel dCity is a multidimensional game viz. higher tax, moderate tax and very low tax game. Elected president can influence the tax rate to some extent and by changing the tax, the rating of the player also changes and ultimately influence the income of the player. From last two time 
One who were focusing on only tax refund and war share will be highly impacted with new tax policy of the president. e.g. in jelly13's presidential period, my income rating was 37 and income was around 0.8Hive and 500SIM daily, which is now reduced to less than 0.1Hive, but SIM income has become doubled. Overall, my income in reduced.
This will be keep changing all the time as new president elected every 14 days. For serious players who want to keep maintaining their income to a certain level, must have to think in all direction and build city accordingly. Because it is not possible to change strategy with a changing president all the time.
Now due to lower taxes there are chances to earn SIM income, so we can clearly see the impact on the market. This morning when I check the market observed that most of the high income generating cards are in demand and as a result their price have gone up. Here I took screenshot of such cards 👇
Most 3rd edition cards, which were not in much demand till yesterday, now become favourite of the players. They are buying such cards on market price, so price is increased. Today I also bought such cards which were looking undervalued as per their income value.
This moderate tax regime will be most beneficial for new players, as they would be able to generate some SIM income with low investment in the game. But at the same time due to more SIM printing chances of inflation will be high, and the SIM price can be dropped.
For new and serious players, it is time to build the city by reinvesting SIM income in the game. I think strategy must be multidimensional. Before buying any card, we must calculate all attributes of the card as with income, creativity, population, education, and popularity must be considered to build a sustainable city in long term.
One thing is clear from the game ecosystem, that short term vision in the game can't make the game profitable and sustainable. Playing very fast without any good strategy will also be a reason to lose interest in the game.
(Above all are my personal view, not a financial advice)
