Proverb for Someone will work, but another will get the benefit

Can you suggest what would be a good proverb for "Someone will work, but another will get the result"? Like for the situation when one person does the hard work, but some other reaps the benefits.

EDIT:

Just wanted to mention that I just meant a single line proverb that is commonly used for the above situation in English speaking countries. For example a proverb like: "The opera ain't over till the fat lady sings."

Solution 1:

The one you come very close to:

“One sows and another reaps.”

[Jesus] [John 4:37] [Amplified Bible]

Solution 2:

A suitable proverb may be found in the moral to Aesop's fable The Lion, the Bear, and the Fox. The fable itself is about a bear and a lion who fight over food and lose it to a fox who takes advantage of their inattentiveness. (So in my estimation a better moral might be something like "Quit while the going's good.") But the moral according to several sources is:

It sometimes happens that one man has all the toil, and another all the profit.

or more pithily as:

Those who have all the toil do not always get the profit.

About a similar fable's moral Wikipedia says

The moral [Austrian poet Candidus] Pantaleon draws at the end is Saepe alter alterius fruitur labribus (from the labours of others it is often another who profits).

Comedian George Carlin is cited as offering the following humorous and modern take on this phenomenon:

“The caterpillar does all the work but the butterfly gets all the publicity.”

(This may not be ideal in this question's case, since the caterpillar and the butterfly are in reality the same entity.)

Solution 3:

For this type of question, the obvious point of reference is country music. Travis Tritt said it best in his song, "Lord Have Mercy on the Working Man":

"Why's the rich man busy dancing, while the poor man pays the band? Oh they're billing me, for killing me. Lord have mercy on the working man!"

Solution 4:

Jesus said to his disciples,

"I sent you to reap what you have not worked for. Others have done the hard work, and you have reaped the benefits of their labor" (John 4:38 NIV).

If I were to put his words into a proverb, it would be

"Sometimes you reap what other people have sown."

Or,

The farmer says, "Now that I've done the hard work, I will wait patiently to reap what I've sown." The fool says, "Now that others have done the hard work, I can't wait to reap what they've sown."
