Offtop:
thanks qb. and spy - its good to come back to your comments. 
on another note, san fran has one of the most inflated real estate markets in the US so it's understandable it's more expensive than many cities.
question:
when it comes to migration, the topic is better discussed between countries and people of eastern europe, is it not?
i mean, it is only more of a problem there because the countries are small and next to each other. that is, if i were living in france and moved to spain, that would be my immigrating to spain. i dont know if i'd say i migrated to spain from france. that just sounds weird. but i guess it's all semantics anyway.
