One approach which was partially successful was initiated by Israel in
the early l970's, called the 'build your own home' program. A half a
dunam of land outside the camps was given to a Palestinian who then
financed the purchase of the building materials, and usually with
friends, erected a home. Israel provided the infrastructure: sewers,
schools, etc. More than 11,000 camp dwellers were resettled into ten
different neighborhoods before the PLO, using their time-honored
tactics of intimidation, ended the program. The Israeli authorities
would say that if the people were able to stand up to the PLO within
eight years every camp resident could own a single dwelling home in a
clean and uncongested neighborhood.

Jesus spoke English, and that's good enough for me.
