I do not know whether I am correct or not, and of course I would be very interested for your views. Looks like the issue with the roma people in Bulgaria is much the same with Greece. We have them, and whether prejudice or not here they are accused in much the same way some people do with their Bulgarian counterparts.
IMO the issue is not exactly the roma or financial immigrants or whatever. Problems with robberies, violence etc occur when the gap between those who have and those who have not crosses some threshold. For wherever poverty or wealth are uniformly distributed there is little crime.
Bulgaria's main attraction as a residential country is that living costs are relatively low. Had it not been so, then most probably the majority of you would not be there.
Yet the reason behind those low living costs has been that fundamentally the people of this country are so poor. Which makes us foreigners look rich by comparison.
Have seen some properties fitted with iron bars behind every window or door. While I am not in a position to judge their effectiveness, I would not favour to live imprisoned behind bars.
In theory the obvious way is to get yourselves Bulgarianized. Is this feasible and how? Have you thought of alternatives and which?
