136 We have also observed with great pleasure the praiseworthy steps various nations have taken with regard to this important matter. A number of countries have recently adopted a common plan and program to bring this critical problem to a swift and happy conclusion. We trust that these measures will make it possible for emigrants to enter those lands in greater numbers and with greater ease, but we are even more concerned that they provide for the happy reunion of parents and children as a family unit. Once these sound steps are taken, it will certainly be possible to make adequate provision for the needs of the emigrants, in religion, in morals, and in economic matters; and this, in turn, will benefit the countries which receive them.
