Prices are low because spirits are, to make them high again we have to raise spirits by raising prices.
The bankers lost all our money buying worthless things for trillions, so the economy's shrinking and we're all upset. To fix the problem we as a state have to borrow our future money (and print money) to give the banks (and to ourselves directly) so we don't lose all our money and so we exchange it with one another. We can afford to borrow our future money because in the future the economy will be growing, so we will have more money, because we will have exchanged with one another our future money, therefore will be happy.
When because we're feeling better we have money again, we will all feel better, perhaps as good as before, when we felt so good we lost our money, and became sad.
