Proverbs 15:6 (ESV)

6 In the house of the righteous there is much treasure, but trouble befalls the income of the wicked.

Infinitely precious treasure is in the home of the righteous because, even in the small, humble house, the infinite and eternal God in Christ is pleased to live in the hearts and homes of believers. By our having Him, all other things become a blessed abundance (Philippians 4:11–13). By contrast, whatever comes to the wicked, however abundant and materially valuable, is tainted by the sin of the one who receives it, and so it is transformed into trouble.
