You can see different degrees of "house-pride" in the US among some of the more recent Hispanic immigrants. For example, Cubans are generally very "house-proud", even among those that are relatively less affluent than the average population. Puerto Ricans and Mexicans are not very "house proud" compared to Cubans. You see it among poor, even middle income Blacks, even if they own their houses. Its the difference between the relatively more ordered Judeo-Christian cultures of the Japhetic peoples of the Northern Hemisphere and the relatively less ordered pagan cultures of the Hametic peoples of the Southern Hemisphere.
Anyway, I hope you make this known to Michael Freund and other that are engaged in helping the lost tribes to come to Israel. They should know so that they can help to socialize these people before they bring them to Israel.
