I mean, this is a very good philosophy to have.

The trouble is, the people who are most vocal about "no poors allowed" emphatically do not subscribe to it, and the people who are most likely to have power over these things do not subscribe to it (there is some, but not perfect, overlap between these groups).

And it's kinda tricky to go over their heads and get rules put in place at the next level above them (ie, the level that sets the rules they have to follow) that can effectively prevent this sort of thing.
