Ecclesiastes 5:10 & 11

"Whoever loves money never has money enough; whoever loves wealth is never satisfied with his income. This too is meaningless. As goods increase, so do those who consume them. And what benefit are they to the owner except to feast his eyes on them?" NIV translation

Solomon was probably the richest man the world has ever seen and yet this is what he found out about the pursuit of wealth. After you have what you need to survive, the rest is usually just put on display as he says here. In the end, those things are not going with you (whether you go to heaven or hell).

Ecclesiastes 5:12

"The sleep of a laborer is sweet, whether he eats little or much, but the abundance of a rich man permits him no sleep." NIV translation

Since the fall of man (Genesis 3), Adam and his descendants (all of us) have had to work for our food. Solomon found that the man that works for what he has sleeps better than the rich man. It seems that the rich man becomes a hostage to his wealth and constantly worries about someone stealing from him or how he can get more.

Ecclesiastes 5:13 - 15

"I have seen a grievous evil under the sun: wealth hoarded to the harm of its owner, or wealth lost through some misfortune, so that when he has a son there is nothing left for him. Naked a man comes from his mother's womb, and as he comes, so he departs. He takes nothing from his labor that he can carry in his hand." NIV translation

Wealth is fleeting and Solomon came to realize that we do not create anything and are not taking anything with us when we die. How sad it is to see someone who seemingly has everything that this world has to offer but they do not have what is important and eternal. When they stand before the Judge, they will not have anything in their hands and, without the love of God in their hearts, they will be doomed.
