I hope people read past comments before posting "newspapers are more expensive to upgrade than oil companies". This is intended and is explained by the devs. Newspapers have a higher multiplier than the oil companies. I know this has been stated loads of times, but I think other people don't know how to check past comments. Stop complaining about the newspapers. This is not a bug. They are supposed to be more expensive to upgrade when you reach 300+.

Dude, how did you think that "speed of profits doubled" means that the profit time takes twice as long? Twice the speed of profit means that it takes half of the original time it took.
