Buenos Aires is not Lagos and it is not Helsinki, either.
Buenos Aires is also not Nairobi, Kiev, Tallinn, Macau, Hangzhou, Yangon, Carson, Younkers, Tirane, Zagreb, London, Hamburg, Stockholm, Madrid, Baghdad, Lahore, New Delhi, Colombo, Johannesburg, Sydney, Casablanca ........
It is Buenos Aires. It is what it is. If you don't like it, I don't get the feeling there are chains around your feet; you can fix it, fix what you don't like, or you can go somewhere else you think will offer you a better life, or you can just whine about it.
Look at the recent poll about safety in this city. There seems to be some disagreement. There are people who are paranoid in general, there are people who have become paranoid because something bad happened to them, there are people wearing rose-colored glasses, there are realists, there are chicken littles, there are people who like to just make the best of whatever place or situation they find themselves in .....
All kinds visit here.
I don't think it is hard at all to read between the lines, or simply just read the lines themselves, to see what agenda the message arises from.
But let's just accept that this is Buenos Aires and not some other place, and live here or not. If you have the power to fix its problems, then jump right in. I won't stop you.
