Jesus entered the temple and drove out all who sold and bought in the temple, and he overturned the tables of the money-changers and the seats of those who sold pigeons. He said to them, “It is written, ‘My house shall be called a house of prayer,’ but you make it a den of robbers.” –Matthew 21:12-13 (ESV)

A false balance is an abomination to the Lord, but a just weight is his delight. –Proverbs 11:1 (ESV)

Building wealth by advertising to find customers for your own business; and accumulating amounts of money from customer payments alone. Investments are discouraged as high risk and dangerous. The general mentality of responsible small business owners in Little House on the Prairie times, was to grow rich by aggressively saving business income alone; and avoiding all forms of investing, especially stocks (p. 311). The goal was to accumulate an emergency fund by saving 20% a week; and purchasing a farmhouse in cash (pp. 241, 271).
