For not from the east or from the west
and not from the wilderness comes lifting up,
but it is God who executes judgment,
putting down one and lifting up another.
In Proverbs we are taught that "the mouth of a fool brings ruin near" (Prov.10:14-16) and that "poverty and disgrace come to him who ignores instruction, but whoever heeds reproof is honored" (Prov. 13:18). Additionally, a foolish man "devours" what treasure and oil is in his household (Prov. 21:20), and a woman's folly will destroy her own house (Prov. 14:1).
The bottom line is that a general consequence of foolishness is impoverishment. One reason some people are poor, consequently, is that they ignore God's instruction and they instead lead wanton, profligate lives. A 2004 study by the National Poverty Center, for example, found that substance use and abuse was an important "barrier to self-sufficiency" and hence a contributor to poverty. Again this does not mean that all poor people are immoral and foolish. It is to say that there are often negative economic consequences to foolish behavior.
