I quite agree with you about the "collective mindset" problem. It's got so bad that even a President with 'good intentions' cannot really steer Nigeria out of the current mess.
I honestly don't know what would save us. Until then, the people who really want to make some good life while in Nigeria will do so, and those who can't will be pressured to leave.
And of course those who can't leave will either resort to something either good or bad to remain 'alive'.
May a miracle or a true revolution happen someday🙏
