What is the meaning of "rake in the bucks"?

Question

I've read the phrase in a post by Joel Spolsky:

You should be starting to get some ideas about how to break the chicken and egg problem: provide a backwards compatibility mode which either delivers a truckload of chickens, or a truckload of eggs, depending on how you look at it, and sit back and rake in the bucks.

I somehow feel that the meaning is:

• You earn so much money that you have to collect them with a rake.

or

• You will see money as leaves on the ground (because you have so much of it) and you will collect them with a rake.

We have an equivalent phrase in our language (Persian) that refers to someone who has a lot of money, and says he shovels the money.

How much am I right?

Answer 1

It is an idiomatic expression that means earn a lot of money. Sit back and rake in the buck, that is relax and bring home the money.

Rake in:

• earn large sums of money; "Since she accepted the new position, she has been raking it in"

Buck:

( Informal)

• A dollar.
• An amount of money: working overtime to make an extra buck.
