Investors

Investors permanently increase the production bonus that each Army Contractor gives.

They cost gold to hire, and are a very good way (if not the best) to spend your gold. After the investor that costs 26k gold coins, there are 2 more investors with even higher benefits and prices, but you need to hire the previous investors in order for them to show up.

Investors stay with you through the three Prestiges:
 * Deploying
 * Privatization
 * Change of Boot Camp
