every decade, only a handful of worthy (not just rich) people obtained UAE citizenship. The telegram founder became a citizen.
Singapore's context - a handful of people per hour.
It is by their country special invitation only, not like us ... submit application form to be granted.
That is the difference. Also no doubt UAE citizens are small percentage in their own country, they are never bullied by foreigner.
We have yet to read any news that drunk foreigner Angmo bash up the Arabs & gotten away with just a light wrist slap
