Forget all that about bulldozers. This is not USA.
Despite the people with bad attitude, which surely is consequence of real-life crime rooting on slums and causing understandable fear, Argentina is not xenophobic, and is proud of being solidary, compasive and humanitarian.
This is not the first wave of indigenous migration to Argentina, and will not be the last. Argentina on the past reacted giving them land, houses, health care and education. That’s why they keep moving to Argentina.
On USA, they would be detained, incarcerated, and deported, but not here. There are no illegal immigrants on Argentina. Only undocumented.
Muslims are not molested about their right to build mosques like in New York. They are not forced to dress like French like in France. As consequence, they integrated, and you can’t tell the difference between a Muslim Argentine and other origins. They do mosques wherever they want, and nobody cares. I know a Jew architect who designed a mosque in Córdoba.
USA and Europe don’t understand that to integrate foreigners they should be accepted as they are. Integration is not about enforcing your customs and viewpoint. It’s about being welcoming and friendly.
The people calling Argentines xenophobic, on base of a limited experience, are xenophobic themselves.
Slums exist because Argentina has being not able to sustain the migratory pressure, and economic difficulties (both for internal and external causes) do not allowed to absorb the new citizens, but world reality is changing, and Argentina may be able to recover.
In the past, Indo-American and European migrants were given land, houses, and all the benefits. They prospered making this country one of the richest. It makes new citizens productive; it’s an investment.
