The irony. You started with an ignorant comment to show how far from ignorant you are. So ignorant AND dumb.
Anyway, The population of Nigeria is 206 million. And there are 250 thousand Nigerian-born immigrants in the US.
https://blog.remitly.com/immigration/nigerian-immigration/. That's 0.1% of the population "trying hard af" to move to the US.
0.1%. Zero point one percent.
Their current total migration rate is -0.3 per 1,000 people.
https://www.cia.gov/the-world-factbook/field/net-migration-rate/country-comparison. That's -0.03%. So 0.03% are "trying hard af to leave to never come back" lol. Yeah, it could be better, but relatively speaking, it's still better than 121 other countries on that list.
You can go ahead an air out everything bad you can find on Nigeria. Only the dumb dumbs of bgol will eat it up anyway.
