Rwandan Marriage vs Western Marriage (U.S.)

After researching various Rwandan marriage practices and institutions, I found it interesting the cross-cultural differences between their rituals, their resonings, and there methodology compared to ours here in the United States.
Here in the U.S., we seem to take for granted the idea of marrying the one we love, the one we want to be with, the one for us. In Rwanda, though mate selection is now an accepted practice, arrainged marriages and family approval of a wife or husband is still wide spread. Rwandans see marriage as a means to an end. A union is generally designed to further kinship and societal ties. By the age of 45, 90% of all men are married. Being married, as well as having a large family structure, is seen in Rwanda as a sign of wealth.
It strikes me the difference in our culture today. While it is true that being married is a sign of stability, at least in some circles, being single is not looked down upon or considered strange as it is in Rwanda. Marriage here, as there, is a sacred rite, and taken very seriously, but for very different reasons.
