We need to work, yes. But not putting in “labour” (much effort) for the purpose of “getting rich” as this verse warns against such ‘common man-made (own) wisdom’:
“Labour not to be rich: cease from thine own wisdom.” (Proverbs 23:4)
It is good therefore to work sufficiently (and “not” overly) & be content in whatever state we are in.
Notice that the world often teaches the exact opposite namely:
‘work hard to be rich’
‘work till your bank balance looks like a phone number’
‘while others are sleeping, I am still working’
