Housing policies can be used to promote multiculturalism. To the extent that we can get people from different cultural backgrounds to live together, in the same neighborhoods, that would be a huge step forward towards forging genuine multiculturalism. Currently, we have a situation where people from the same cultural backgrounds tend to live in the same neighborhoods. Very few neighborhoods can be said to be genuinely multicultural. You go to a certain neighborhood, and you find that most of the people there are from a certain cultural background. There may be a few people from other cultural backgrounds, but most of the people are from a certain cultural background. And the trend is the same in almost every neighborhood you visit.
A deliberate attempt has to be made, through housing policies, to get people from different cultural backgrounds to live together as neighbors. I think I got this idea (that housing policies can actually be used to promote multiculturalism) from a CVS Learnet tutorial, and I reckon that it makes a lot of sense.
There are several levels at which the housing policies can be used to promote multiculturalism. At the land allocation point, for instance, an effort can be made to ensure that land is allocated to developers from various cultural backgrounds. Chances are that those developers would then rent out or sell the houses they develop to people from their respective cultural backgrounds. And because the land was initially allocated to developers from different cultural backgrounds, the people who end up renting or buying those houses would (most probably) be from similarly different cultural backgrounds. The end result would be that of genuinely mixed neighborhoods.
It is, of course, important to educate people on multiculturalism, to get them to a point where they can be okay with the idea of living close to people from other cultural backgrounds. Currently, we see people with huge prejudices, which make them very uncomfortable whenever they have to interact closely with people from different cultural backgrounds. It is only through multiculturalism education that we can overcome such prejudices.
