I notice something similar in Jordan some time ago.

Jordanians were very angry against iraqui, because during and after Gulf War they arrived Amman looking for safety with big wallets plenty of dollars... and they made every single price to rise...

Overall they were very angry because of the schools. Iraquis took the best schools for their children and public schools were absolutely crowded...

It is not exactly "buy the citizenship" but "buy the safe"

War looking for peace,
is like fornication looking for virginity.
