If I give you 5 trillion dollars I want to get that back plus a percentage increase on top for my troubles, right? Government programs might run without the expectation of paying back taxpayers but investors are less generous.
Also they might not be as smart as they have made out to be. This time it seems they might be spending more to capture market than the market is worth.
Still, there are plenty of people who take their cut of the money on the way. So at least those people will be happy.
