Is there such a thing as 'Economic Discrimination'?

In society many forms of 'discrimination' have been outlawed. What has (seemingly) evolved as a result is greater economic distinction, whereas the gap between the 'have's' and the 'have-not's' has become increasingly prevalent. 'Good' neighbourhoods, excellent schools, advanced city services, medical treatment availability, adequate police and fire service, are all (again, seemingly) decided by affordability. Those who are 'high' on the economic scale can access those services. Those who are not cannot. Is this a form of discrimination?
