Hi, playing a demo cashier and have +183% science in business and residential. I feel like im throwing money away trying to get to 188% each. Does this ever compete with REP's +20% PCI?  
 
It is worth it to get to about 186% once you're stockpiling.  While you're growing, even getting over 180% means that you're growing too slowly.

demo is good as casher but rep is better. 
 
Republic is better unless you know how to play the market properly.  If you know how to make a profit reselling, and to protect your stockpile from devaluing during the food crash, then democracy will come out ahead.
