Private Property and Thanksgiving

Were the Pilgrim's saved by an abandonment of collectivism and an embrace of private property? This post, found via the a link in the Volokh Conspiracy, says yes.

Many people believe that after suffering through a severe winter, the Pilgrims’ food shortages were resolved the following spring when the Native Americans taught them to plant corn and a Thanksgiving celebration resulted. In fact, the pilgrims continued to face chronic food shortages for three years until the harvest of 1623. Bad weather or lack of farming knowledge did not cause the pilgrims’ shortages. Bad economic incentives did.

Faced with potential starvation in the spring of 1623, the colony decided to implement a new economic system. Every family was assigned a private parcel of land. They could then keep all they grew for themselves, but now they alone were responsible for feeding themselves. While not a complete private property system, the move away from communal ownership had dramatic results.
This change, Bradford wrote, had very good success, for it made all hands very industrious, so as much more corn was planted than otherwise would have been. Giving people economic incentives changed their behavior. Once the new system of property rights was in place, the women now went willingly into the field, and took their little ones with them to set corn; which before would allege weakness and inability.
