Inequality so unequal, almost needs a new word to describe it. It's beyond comparability at this point.

More simple: you have to pay to reach poor people.

'Sometimes it is the people who no one imagines anything of who do the things that no one can imagine'. Professor Turing, years after his execution, continuing to teach.
