How did the jamestown colony finally achieve prosperity?

Captain John Smith became leader of the Jamestown colony he made a rule that was anyone who did not work did not eat this made the colonists build shelters, plant food so his rule was success

On May 14, 1607, a group of roughly 100 members of a joint venture called the Virginia Company founded the first permanent English settlement in North America on the banks of the James River. Famine, disease and conflict with local Native American tribes in the first two years brought Jamestown to the brink of failure before the arrival of a new group of settlers and supplies in 1610.  

When the colonist John Rolfe married the daughter (Pocahontas) of an Algonquian Chief during the 1620s, Jamestown expanded from the area around the original James Fort into a New Town built to the east; and remained the capital of the Virginia colony until 1699.

its main object was the establishment of "settlement houses" in poor urban areas, in which volunteer middle-class "settlement workers" would live, hoping to share knowledge and culture with, and alleviate the poverty of, their low-income neighbors.
