It is so easy to come up with suggestions not so easy to implement. Out of the area might seem cheaper, but so is the pay while the cost of kosher products is actually more. The cost of chinuch might also be more because the choices are less or kids have to travel much further to get to school. And yes there is also the cost of travel to jobs and to visit family. And as soon as a community starts to get settled with Frum families, the prices start to go up. Moving is also an expense and kids don’t always do so well when they get moved around. It is NOT always such a good option for kids to pick them up and take them away from their friends and family support when they are already in a bad matzav and move them to a completely unknown area.
Really it is not so simple. But if you think that people in trouble don’t think about this and any other option they might have, you are wrong.
