There is a painful tragedy that I have seen under the sun: Riches lead to the downfall of those who hoard them.
These hoarded riches were then lost in bad business deals. The owners had children, but now they have nothing to give them.
They came from their mother's womb naked. They will leave as naked as they came. They won't even be able to take a handful of their earnings with them from all their hard work.
This also is a painful tragedy: They leave exactly as they came. What advantage do they gain from working so hard for the wind?
They spend their entire lives in darkness, in constant frustration, sickness, and resentment.
At last I have seen what is good and beautiful: It is to eat and drink and to enjoy the good in all our hard work under the sun during the brief lives God gives us. That is our lot [in life].
It is a gift from God when God gives some people wealth and possessions, the power to enjoy them, [the ability] to accept their lot in life, and [the ability] to rejoice in their own hard work.
These people won't give much thought to their brief lives because God keeps them occupied with the joy in their hearts.
