"He who Hates Gifts shall Live"

So there's this man, Korah. He has a problem: He sees these Cohanim people working in the holiest place on Earth, and how they constantly have these gifts showered upon them, yet they don't seem to be affected in any way by greed or its like. So he wonders to himself, 'how is possible that these men are always taking from the people yet maintain a level of sanctity which enables them to remain in the service of the Temple?' It doesn't make any sense.
Korach's nature is so wrapped up in 'taking' that he can't conceive of how it's humanly possible to overcome such a tendency without heavenly assistance, which the Cohanim obviously had. So he becomes jealous and complains to Moshe saying, "How come Hashem chose them and not me? Why should I have to suffer from this affliction of 'taker-man' while these Cohanim people get to enjoy Hashem's bounty with seeming ease?" So Moshe responds, "If you feel that you need to take, then take for Hashem."
"What are you talking about?" Korach muses.
"Actually, it's quite simple." Moshe responds. "Haven't you ever heard of 'serving God with your evil inclination'?" "Easier said than done." Korach snaps, with a growing impatience. "And another thing," He continues, "I've been working on myself for years now and nothing seems to have changed, while these Cohanim get a power boost for free! It's just not fair!"
Moshe saw that Korach's intentions were distorted. Instead of turning to Hashem for assistance, he trusted in his own strength and determination. If he would only stop and think for a moment, he would realize that his strength and determination are themselves gifts from Hashem, which would then open him to receive more as well.
Korach's problem was foreseen by Hashem and implied in his name, which in Hebrew is made up of the three letters Kuf, Raish and Chet. The two extremes spell 'Kach', or 'take'. But if he were to focus on the 'middle' path, the Raish (head) he would quickly realize his mis-take. The message of the Cohanim is that man's ability to work is itself a gift from Hashem, and until Korach realizes that taking just doesn't work, rather he must transform this desire into a willingness to receive, nothing will work out for him.
The Earth itself tries teaching him this lesson by opening up to 'receive' him and all he has taken.
It's not about freebies either. The Cohain is someone who lives with the true awareness of what it means to receive in order to give. Our job on planet Earth, Hashem's kingdom, is to ready ourselves to receive. The more we can adjust our attitudes towards the awareness that all is a gift, the sooner we will merit to live up to our potential of being a 'Kingdom of Cohanim' and serve Hashem in the third Temple, may it be built speedily in our days, Amen.
