In the beginning of the movie, the funding for the Jaeger program is being cancelled, because they aren't good enough. Pentecost however, says he doesn't need his financiers, he's going to go on anyway.
So where does he get the money? From his own purse? Is he really that rich?
I know, usually finances don't really play that great a role in this kind of movie. But in this scene, they make it very clear that withdrawing all the funding will effectively bring the program to a halt, and Pentecost's reaction of "no it won't" made me wonder.
