It rains where it’s already wet!

I went to the office of an air company to ask information regarding a ticket to Europe.
They were kind and efficient.
I asked about possible discounts and they answered that special prices are available for diplomats and UN people.
An ill-proportioned salary and a combination of different privileges are not sufficient for them, they also pay less to travel.
The existence of those advantages, benefits and rewards tend to reproduce that world where someone is in and the others stay out.
It appeals to factors stronger than the financial ones, those of status, class, privilege.
