Consider the limitations the Law of Moses placed on Israel and Judah, had they chosen to follow it with any consistency.
The usury laws and the Jubilee would curtail the ability of merchants and profiteers to exploit the lack of financial sophistication among their fellow Israelites. Israel’s law forbade certain forms of lucrative trade: fortune telling, the manufacture of graven images, cult prostitution. The Sabbath laws would restrict commerce to six days a week rather than seven. Tithing obligations would take well over 10% of your income, and the law would permit, even encourage, the poor and the sojourner to help themselves to the excess of your fields and vineyards.
In short, when the provisions of Mosaic Law were observed and enforced, Israel was not the easiest place in the world of its day for profiteers and merchants to get rich quick. That said, it was a great place to live for normal, godly people.
