Yes, and it isn't delegated just to the rich. I've said it before and I'll say it again. When you really get down to where the rubber meets the road, rich is defined as anyone that has more than [fill in your name] do. Its the same old parable of the workers in the vineyard. See Matthew 20:1-16. We get jealous when we learn that someone else is doing better than we are and we covet what they have. Scripture tells us to be content with what we have and to work for what we want.
11 Not that I am speaking of being in need, for I have learned in whatever situation I am to be content.
12 I know how to be brought low, and I know how to abound. In any and every circumstance, I have learned the secret of facing plenty and hunger, abundance and need.
13 I can do all things through him who strengthens me.
Philippians 4:11-13 NKJV
5 Keep your life free from love of money, and be content with what you have, for he has said, “I will never leave you nor forsake you.”
Hebrews 13:5 ESV
31 Therefore do not be anxious, saying, ‘What shall we eat?’ or ‘What shall we drink?’ or ‘What shall we wear?’
32 For the Gentiles seek after all these things, and your heavenly Father knows that you need them all.
33 But seek first the kingdom of God and his righteousness, and all these things will be added to you.
Matthew 6:31-33 ESV
6 Now we command you, brothers, in the name of our Lord Jesus Christ, that you keep away from any brother who is walking in idleness and not in accord with the tradition that you received from us.
7 For you yourselves know how you ought to imitate us, because we were not idle when we were with you,
8 nor did we eat anyone's bread without paying for it, but with toil and labor we worked night and day, that we might not be a burden to any of you.
9 It was not because we do not have that right, but to give you in ourselves an example to imitate.
10 For even when we were with you, we would give you this command: If anyone is not willing to work, let him not eat.
11 For we hear that some among you walk in idleness, not busy at work, but busybodies.
12 Now such persons we command and encourage in the Lord Jesus Christ to do their work quietly and to earn their own living.
2 Thessalonians 3:6-12 ESV
