So your definition of poverty is one where a person remains in poverty for their whole life, so my example of over 70% of people getting out of poverty isnt poverty by your definition by virtue of the fact that they got out of it?
We call that a "No true scotsman" fallacy. By simply stating anyone who ever gets out of poverty was never in it, no matter how poor they were, effectively is just denying the counter evidence and creating a circular definition that says nothing useful.
