[Mass Effect] Where does the Illusive Man get his money?

I know that Cerberus owns many front organizations and cover businesses and was originally a branch of Alliance intelligence, but how do they possibly have the dosh to acquire and cultivate all of their scientific and military talent? How do they finance their fleets of warships and dropships and improbable androids with complex smart AI? 

Inquiring minds demand answers!

Some believe that there are still high ranking members of the Alliance military that are helping to fund them. If the highest ranking person in the entire Alliance was collaborating with them, there's no doubt they had a lot of top tier support in the government. 

Also, they only started fully militarizing right before the Reapers invaded. For the same reason the Crucible was built so quickly, its because money is no longer a factor when you are on the verge of the apocalypse, fighting for pure survival. All that matters is resources and manpower.
