Well, mathematically Q3 and Q5 WRM Companies are the most profitable at the moment, since cc became pretty expensive.
With the highest production and the low current prices of 0,05cc/WRM and 0,3cc/10 foodthealth you earn:
12,2cc/day with Q3 WRM (0,61% of the purchasing price - 163 days to get your invested money back (200cc/gold))
24,7cc/day with Q5 WRM (0,35% of the purchasing price - 283 days to get your invested money back)
Also there were times when the RM Companies were 40% cheaper, which makes them highly profitable.
Q5 might be less profitable than Q3 in normal cases, because of their cost/production rates, but you need to spend
less health you need in military module and - in rare cases of high demand - you can assign employees on them and earn extra money.
Also a safe way to earn money are Q1 Food Companies. You can buy them anytime for 10 Gold (or less), earn money with them, and, if you need to,
you can sell them for the same price of 10 Gold (or 9.99 works great).
If you buy your raw for expensive 0,03cc each and get 0,055cc per food you produce and consume 5 of them to recover your health,
at maximum productivity you will earn: 4,725cc/day (195*0,055cc - 200*0,03cc)
Thats much less than the Q3 WRM, which is sometimes 40% cheaper, but you can get your invested gold by 99,9% back.
You earn cc without losing gold.
If you are bottlenecked by the 10 Gold/day limit (and have no dealer for gifted gold for cc^^) Q1 Food might be a way to earn extra cc.
Also, if you really have to much gold and companies taking your health, High-Quality companies might be useful.
Q6 Food or Q7 Weapons are perfect, but only purchase them if they are 45% off...
You can earn more cc for your own health and sometimes earn money by using workers.
Even more, when you hire more of them as you need, when they are cheap.
