In French there's a saying mettre un peu de beurre dans les épinards which, literally translated, means to put some butter in the spinach. It's an idiom that describes money improving one's situation.
What idioms in English are there that describe this?
For example, greasing one's pockets can be interpreted as improving someone else's situation, but it wouldn't be used in a sentence like winning this bonus will ????????? and make you richer.
