Ecclesiastes 10:16 says,  Woe to thee, O land, when thy king is a child, and thy princes eat in the morning!  I don't believe that Solomon was referring to age in years, but in maturity of action concerning the way they rule.  If all the people in power are more concerned with meeting their own needs than they are in helping those they govern, then they are acting like a child.  A mature leader cannot act on simply what they want, but must look to what is best for those that they govern.  When leaders are more concerned for themselves than the nation as a whole, even those who may not agree with them, then the nation does live in woe.  Verse seventeen continues this thought stating, Blessed art thou, O land, when thy king is the son of nobles, and thy princes eat in due season, for strength, and not for drunkenness!  I don't believe this means that we are to have a line of nobility to rule over us, but that we are blessed when we have leaders that are taught nobility of spirit.  We need leaders that look beyond what they may want to what will be best for the nation.  When we have leaders who are not controlled by their own appetites, but by living in moderation in their actions, we are blessed.  Verse eighteen says, By much slothfulness the building decayeth; and through idleness of the hands the house droppeth through.  When a person, or a nation, begins to live in a lazy manner, not taking care of their houses or even the structure of the government itself, it will soon collapse.  We are not called to ignore the world, but to care for it.  Verse nineteen says, A feast is made for laughter, and wine maketh merry: but money answereth all things.  I don't believe Solomon is saying that money is the answer to all problems, but that it is better for meeting the needs of life than feasting or wine.  Those things may be enjoyable, but money can be used to meet the needs of life.  We are charged with using it wisely.  Verse twenty says, Curse not the king, no not in thy thought; and curse not the rich in thy bedchamber: for a bird of the air shall carry the voice, and that which hath wings shall tell the matter.  We are not called to curse those in power or the rich, but to pray for them continually that they will follow God in all their actions.
